Joe M. Regenstein, Professor of Food Science Note: This article was
adopted from a previous document focused on poultry. It focuses more on kosher,
since other articles on this site deal with halal. The
kosher dietary laws determine which foods are "fit or proper" for
consumption by Jewish consumers who observe these laws. The laws are Biblical in
origin, coming mainly from the original five books of the Holy Scriptures.
Over the years, the details have been interpreted and extended by the
rabbis to protect the Jewish people from violating any of the fundamental laws
and to address new issues and technologies. The Jewish laws are referred to as
the “halacha.” The
Muslim halal dietary laws determine which foods are acceptable to Muslims. These
laws are found in the Quran. Again,
Muslim leaders have interpreted these laws over the years. Islamic law is
referred to as Shari’ah. It is eternal: definite and unalterable; yet it is
ever fresh and resilient: applications are adjusted to different times and
circumstances. For example, both the Jewish rabbis and Muslim Imans and Mullahs
are currently dealing with issues related to biotechnology (see below). Why
do Jews follow the kosher dietary laws? Many explanations have been given. The
following by Rabbi Grunfeld is possibly the best written explanation and
probably summarizes the most widely held ideas about the subject (Grunfeld,
1972). Although this explanation is
also relevant for halal, it is important to note, that unlike the kosher laws,
the health aspects of eating are an important part of the halal laws. For a
discussion of the kosher laws and health, please see Regenstein, 1994.
“And ye shall be men of a holy calling unto Me, and ye shall not eat
any meat that is torn in the field" (Exodus XXII:30). Holiness or
self-sanctification is a moral term; it is identical with...moral freedom or
moral autonomy. Its aim is the complete self-mastery of man.
"To the superficial observer it seems that men who do not obey the
law are freer than law-abiding men, because they can follow their own
inclinations. In reality, however, such men are subject to the most cruel
bondage; they are slaves of their own instincts, impulses and desires. The first
step towards emancipation from the tyranny of animal inclinations in man is,
therefore, a voluntary submission to the moral law. The constraint of law is the
beginning of human freedom....Thus the fundamental idea of Jewish ethics,
holiness, is inseparably connected with the idea of Law; and the dietary laws
occupy a central position in that system of moral discipline which is the basis
of all Jewish laws.
"The three strongest natural instincts in man are the impulses of
food, sex, and acquisition. Judaism does not aim at the destruction of these
impulses, but at their control and indeed their sanctification.
It is the law which spiritualizes these instincts and transfigures them
into legitimate joys of life."
The
Kosher and Halal Market The kosher market covers almost 100,000 products in
the US. In dollar value about 100 billion dollars worth of products have a
kosher marking on them. The actual consumers of kosher food, i.e., those
who specifically look for the kosher mark, are estimated to be about 6 to
8 million Americans and they are purchasing almost 3 billion dollars worth
of kosher product. Only about
1/3 of the kosher consumers are Jewish; other consumers include Muslims,
Seventh Day Adventists, vegetarians, people with various types of allergy,
particularly dairy, grain, and legume, and general consumers who value the
quality of kosher products: "We report to a higher authority."
AdWeek Magazine has called kosher "the Good Housekeeping Seal for the
90s." By undertaking kosher certification, companies can
incrementally expand their market by opening up new markets. The Muslim market in the US is just emerging. Many
urban centers have special halal markets, and most Muslims observe the
halal laws. But the real opportunities exist on a worldwide basis -- the
number of Muslims in the world is around 1 billion people. Many countries
of Southeast Asia, the Middle East, and Northern Africa have predominantly
Muslim populations. In many
countries, halal certification is necessary for products to be permitted
to be imported. Although many Muslims purchase kosher food, these
foods, as we will see below, do not always meet the needs of the Muslim
consumer. In particular the use of various questionable gelatins in
products produced by some kosher supervisions and the use of alcohol (many
are permitted in kosher food, if properly prepared) are areas of
difference. Although limited market data is available, the most
dramatic data about the impact of kosher has been provided by Coors when
they went kosher. According to their market analysis, their share of
market in the Philadelphia market went up 18% on going kosher. Somewhat
less dramatic increases were observed in other cities in the Northeast. The Kosher Dietary Laws The kosher dietary laws predominantly deal with three issues, all in the animal kingdom: A. Allowed Animals. However, for the week of Passover (in late March or
early April) restrictions on "chometz," the prohibited grains
and the rabbinical extensions of this prohibition leads to a whole new set
of regulations, focused in this case on the plant kingdom. In addition there are a separate set of laws dealing with grape juice, wine, and alcohol derived from grape products. Basically, these must be handled by sabbath-observing Jews. However, if the juice is pasteurized (heated or "mevushal" in Hebrew), then this juice can be handled as an ordinary kosher ingredient. Allowed Animals and Prohibition of Blood Ruminants with split hoofs, the traditional domestic
birds, and fish with fins and removable scales are generally permitted.
Pigs, wild birds, sharks, dogfish, catfish, monkfish, and similar species
along with all crustacean and molluscan shellfish are prohibited. Insects
are also prohibited so that carmine and cochineal (natural red pigments)
are not used in kosher products. With specific respect to poultry, the traditional
domestic birds, i.e., chicken, turkey, squab, duck, and goose are kosher.
Birds in the rattrie category (ostrich, emu, and rhea) are definitely not
kosher as the ostrich is specifically mentioned in the Bible (REF).
However, it is not clear as to whether the animal of the Bible is the same
animal we know as an ostrich today. Regardless these and most other birds
are prohibited. There have
been some attempts to characterize the features that make a kosher bird,
but these are not widely accepted and basically one relies on
“tradition.” Interestingly, domesticated turkey is considered kosher
although wild turkey may not be. Part of the problem is that “hunting”
is not permitted under any circumstances. Furthermore, ruminants and fowl must be slaughtered
according to Jewish law by a specially trained religious slaughterman.
These animals are also subsequently inspected by the rabbis for
various defects. In the US, the desire for more stringent meat inspection
requirements has led to the development of a kosher meat meeting a
stricter inspection requirement, mainly with respect to the lungs,
referred to as "glatt (smooth) kosher." This mainly refers to
red meats where lung adhesions are a problem and often make an animal not
kosher (treife). In general a glatt kosher animal’s lungs have less than
3 such adhesions. As it is difficult to examine the lungs of poultry, this
is not generally done. Yet, to distinguish poultry products as being
produced to a sticter standard, some producers will also use the term “glatt.” The meat and poultry must be further prepared by properly removing certain veins, arteries, prohibited fats, blood, and the sciatic nerve. In practical terms this means that only the front quarter cuts of red meat are generally used. Again, a minimal set of rules apply to poultry. To remove the blood, red meat and poultry are soaked and salted within a specified time period. Furthermore, any materials that might be derived from animal sources are generally prohibited because of the difficulty of obtaining them from kosher animals. Thus many products that might be used in the dairy industry, such as emulsifiers, stabilizers, and surfactants, particularly those that are fat-derived, need careful rabbinical supervision to assure that no animal-derived ingredients are used. Almost all such materials are also available in a kosher form derived from plant oils. Prohibition of Mixing of Milk and Meat "Thou shalt not seeth the kid in its mother's milk." This passage appears three times in the Torah (the first five books of the Holy Scriptures) and is thus taken religiously as a very serious admonition. The meat side of the equation has been rabbinically extended to include poultry. The dairy side includes all milk derivatives. To keep meat and milk separate requires that the processing and handling of all products that are kosher will fall into one of three categories: A. Meat products. The latter includes all products that are not
classified as meat or dairy. All plant products along with eggs, fish,
honey, and lac resin (shellac) are pareve. These pareve foods can be used
with either meat products or dairy products, exept that fish cannot be
mixed directly with meat. Once a pareve product is mixed with either meat
or dairy products, they take on the status of meat or dairy, respectively. Some kosher-observant Jews are concerned with the
possible adulteration of kosher milk with the milk of other animals (e.g.,
mare's milk) and as such require that the milk be watched from the time of
milking. This "Cholev Yisroel" milk and products derived from
milk are required by some of the stricter kosher supervision agencies for
all dairy ingredients, so that dairy products would have to meet these
requirements. In order to assure the complete separation of milk
and meat, all equipment, utensils, etc. must be of the proper category.
Thus, if plant materials (e.g., a fruit juice) is run through a
dairy plant, it would become a dairy product religiously.
Some kosher supervision agencies do permit such a product to be
listed as "dairy equipment (D.E.)" rather than
"dairy." The D.E. tells the consumer that it does not contain
dairy but was made on dairy equipment (See allergy discussion below). With
the D.E. listing, the consumer can use the product immediately after a
meat meal, while a significant wait would be required to use a product
with a dairy ingredient. In either case, the dishes would be switched from
meat dishes to dairy dishes. A
few products with no meat ingredients are made in a meat plant (e.g., a
split pea soup), again they may be marked “meat equipment (M.E.).” Kosher observant Jews must wait a fixed time between
meat and dairy consumption. Customs vary but generally the wait after meat
before consuming dairy is much longer (3 to 6 hours) than the wait from
dairy to meat (0 to 1 hour). However, when a hard cheese (defined as a
cheese that has been aged for over 6 months) is eaten, the wait is the
same as that for meat. Thus, most companies producing cheese for the
kosher market age their cheese for less than 6 months. If one wants to make the product truly pareve, the
plant can usually be made pareve by the process of equipment kosherization
(see below). Passover During this holiday which occurs in the spring, all
products made from the five prohibited grains: wheat, rye, oats, barley
and spelt (Hebrew: chometz) cannot be used except for the specially
supervised production of unleavened bread (Hebrew: "matzos"),
that are prepared especially for the holiday. Special care is taken to
assure that the matzos do not have any time to "rise."
In addition, products derived from corn, rice, legumes, mustard
seed, buckwheat, and some other plants (Hebrew: kitnyos) are prohibited.
Thus, items like corn syrup, corn starch, etc. would be prohibited. Some
rabbis, however, permit the oil from kitnyos materials. Some rabbis permit
liquid kitnyos products such as corn syrup. The major source of sweetners
and starches generally used for Passover production of "sweet"
items is either real sugar or potato-derived products. Some potato syrup
is also used. Passover is a time of large family gatherings. However
because of the need for separate Passover dairy dishes, some kosher
consumers may not use any dairy products. Overall, 40% of kosher sales for
the traditional "kosher" companies occurs during the week of
Passover. Equipment Koshering There are three ways to make equipment kosher and/or
to change its status. Which procedure is required depends on the
equipment's prior production history. Note: After a plant (or a line) has
been used to produce kosher pareve products, it can be switched to either
kosher dairy or kosher meat without a special equipment kosherization
step. The simplest equipment kosherization occurs with
equipment made of materials that can be koshered that have only been
handled cold. These require a good caustic/soap cleaning. However,
materials such as ceramics, rubber, earthenware, and porcelain cannot be
koshered. If these materials are found in a processing plant, new
materials may be required for production and switching between different
status conditions will be difficult. Most food processing equipment is usually operated at
cooking temperatures, generally above 120F, which is defined rabbinically
as "cooking." However, the exact temperature for
"cooking" depends on the rabbi, although an agreement by the
major four American kosher certifying agencies has settled on 120F as the
temperature at which foods are cooked. To kosher these items which have
been used with cooked product, the equipment must be thoroughly cleaned
with caustic/soap. The equipment must be left idle for 24 hr and then the
equipment must be flooded with boiling water (defined between 190F and
212F) in the presence of a kosher supervisor. In the case of ovens or other equipment that uses
"fire," kosherization involves heating the metal until it glows.
Again, the rabbi will generally be present while this process is taking
place. The procedures that must be followed for equipment
kosherization can be quite extensive, so that the fewer status conversion,
the better. Careful formulatiing of products and good production planning
can minimize the inconvenience. Jewish Cooking Depending on what is being cooked, it may be
necessary for the rabbi to "do" the cooking. In practical terms
this is often accomplished by having a rabbi light the pilot light, which
is then left on continuously. In the case of cheese making, a similar concept
usually requires the rabbi to add the coagulating agent into the vat.
However, if the ingredients used during cheese making are all kosher, but
a rabbi has not added the coagulant; then the whey derived from such
cheese (as long as the curds and whey have not been heated above 120F
before the whey is drained off) would be considered kosher. Thus, there is
much more kosher whey available than kosher cheese. Dealing with Kosher and Halal Supervision Agencies Kosher or halal supervision is taken on by a company
in order to expand its market opportunities. It is a business investment
-- which, like any other investment, should be examined critically. In the
era of Total Quality Management, Just-in-Time Production, Strategic
Suppliers, etc., it is appropriate for companies to look carefully at how
they handle their kosher and halal supervision needs. Price alone may not be the best criterion for
selecting a supervision agency. The agency's name recognition may also not
be the most important company consideration. Other important
considerations should include: 1) how responsive is the agency to the
company, both in terms of paperwork handling and in terms of providing
rabbis or Muslim inspectors at the plants as needed,
2) how willing are they to work with the company on problem
solving, 3) how willing are they to explain their kosher or halal
standards and their fee structure, 4) is the "personal"
chemistry right, i.e., are you comfortable with them, and finally 4) what
are their religious standards, i.e., do they meet the company's needs in
the marketplace. One of the hardest issues for the food industry to
deal with in day-to-day kosher activities is the existence of so many
different kosher supervision agencies. Unfortunately, though fewer
agencies exist, halal also has various agencies with different standards.
How does this impact the food companies? How do the Jewish kosher or
Muslim halal consumers perceive these different groups? How do groups
beyond the immediate community feel about the different agencies? Because
there has not been a central authority for many years in either religion,
different rabbis and imans/mullals follow different traditions with
respect to their dietary standards. Some authorities tend to follow the more lenient standards,
while others follow more stringent standards. Given the availability of
choices, the trend in the mainstream kosher community today is towards a
more stringent standard. The Muslim community also seems to be moving
towards tighter standards. One can generally divide the kosher supervision
agencies into three broad categories. First there are the large
organizations that dominate the supervision of larger food companies, i.e,
the OU, the OK, the Star-K, and the Kof-K.
All four of them are nationwide and "mainstream." Two of
these, the OU and the Star-K are communal organizations, i.e., they are
part of a larger community religious organization.
This provides them with a wide base of support, but also means the
organizations are potentially subject to the other priorities and needs of
the organization. On the other hand, the Kof-K and the OK are private
companies. Their only function is to provide kosher supervision.
In addition to these national companies, there are smaller private
organizations and many local community organizations that provide
equivalent religious standards of supervision.
As such, products accepted by any of these mainstream organizations
will be accepted by all other similar organizations. The local
organizations may have a bigger stake in the local community.
They may be more accessible and easier to work with.
Although often having less technical expertise, they may be backed
up by one of the national organizations.
For a company marketing nationally, a limitation may be whether the
consumer elsewhere in the US knows and recognizes their kosher symbol.
With the advent of KASHRUS magazine, and its yearly review of
symbols, this has become somewhat less of a problem. (KASHRUS magazine
does not try to "evaluate" the standards of the various kosher
supervision agencies, but simply "reports" of their existence.
It is the responsibility of the local congregational rabbi to inform his
congregation of his standards. If he does not know enough about the
"far-away" organization, he may be uncomfortable recommending
it.) The second category of kosher supervision includes
individual rabbis, generally associated with the "Hassidic"
communities. These are often
affiliated with the ultra-orthodox communities of Williamsburg and Borough
Park in Brooklyn, Monsey, NY and Lakewood, NJ.
There are special food brands that cater to their needs. Many more
products used in these communities require continuous rabbinical
supervision rather than the occasional supervision used by the mainstream
organizations. The symbols of
the kosher supervisory agencies representing these consumers are not as
widely recognized as those of the major mainstream agencies in the kosher
world beyond these communities. The
rabbis will often do special supervisions of products using a facility
that is normally under mainstream supervision, often without any changes,
but sometimes with special needs for their custom production. The third level are individual rabbis who are more
"lenient" than the mainstream standard. Many of these rabbis are
Orthodox; some may be Conservative. Their
standards are based on their interpretation of the kosher laws. The more
lenient such a rabbi, the more the food processor cuts out the
"mainstream" and stricter markets -- but that is a retail
marketing decision the company needs to make for itself. The Muslim community has only one mainstream agency
at this time, the Islamic Food and Nutrition Council. Other groups are
entering the field, but their standards are not as well defined. However, ingredient companies, should try to use a
"mainstream" kosher or halal supervision agency. To sell
ingredients to most kosher food producing companies will require such
supervision. The ability to sell to as many customers as possible requires
a broadly acceptable standard. Unless an ingredient is acceptable to the
mainstream, it is almost impossible to gain the benefit of having a kosher
ingredient. In a few
circumstances, if the company makes a product that would not be acceptable
to the mainstream kosher supervision agencies no matter what the company
does, then the company might as well use one of the more
"lenient" kosher supervision agencies willing to recognize that
ingredient. In the future companies will have to pay attention to
halal standards. In many cases a few changes will permit kosher products
to also serve the halal community, i.e., the true absence of animal
products (see below for a few kosher exceptions) and care to assure that
any residual alcohol in products is below 0.1%. Again a standard
acceptable in all or most Muslim countries is desirable. When looking for a religious supervision agency, one
must determine the company's priorities and attempt to find a religious
supervision agency that is compatible with these requirements. Like any purchasing decision, time spent in qualifying the
vendor before purchasing is usually rewarded. With respect to interchangeability between kosher
supervision agencies a system of certification letters is used to provide
information from the certifying rabbi to others about the products he has
approved. The supervising rabbi certifies that a particular plant produces
kosher products, or that only products with certain labels or certain
codes are kosher under his supervision. Such letters should be renewed
every year and should be dated with both a starting and ending date. These letters are the mainstay of how companies establish the
kosher status of ingredients as ingredients move in commerce. Consumers
may also ask to see such letters. Obviously a kosher supervision agency
will only "accept" letters from agencies they consider
acceptable. In addition, the kosher or halal symbol of the
certifying agency or individual doing the certification may appear on the
packaging. (In some industrial situations, where kosher and non-kosher
products are similar, some sort of color coding of products may also be
used.) Most of these symbols
are "trademarks" that are duly registered. However, in a few
cases, the trademark is not registered and more than one rabbi has been
known to use the same kosher symbol. With respect to kosher and halal markings on
products, three issues need to be highlighted:
So far the halal community has not gone to a generic halal marking in this country, although this does seem to be used in some other countries.
Important in many food products, gelatin is probably
the most controversial of all modern kosher and halal ingredients. Gelatin
can be derived from pork skin, beef bones, or beef skin. In recent years,
some fish gelatins have also appeared. The first author is currently
involved in research in this area. As a food ingredient, fish gelatin has
many similarities to beef and pork gelatin, i.e., it can have a similar
range of bloom strengths and viscosities. However, depending on the
species from which the fish skins were obtained, its melting point can
vary over a much wider range of melting points than beef or pork gelatin.
This may offer some unique opportunities to the food industry, especially
for ice cream, yogurt, desert gels, confections, and imitation margarine.
These gelatins would be fully kosher and halal,
and acceptable to almost all of the mainstream religious
supervision organizations. Currently available gelatins -- even if called
"kosher" -- are not acceptable to the mainstream kosher
supervision organizations. Many are, in fact, totally unacceptable to
halal consumers because they may be pork gelatin-based. However, a recent
production of gelatin from the hides of kosher slaughtered cattle has been
available in limited supply at great expense, and this has been accepted
by the mainstream and even some of the stricter kosher standards. Among the lenient kosher supervision agencies, one
finds a wide range of attitudes towards gelatin. The most liberal view
holds that gelatin, being made from bones and skin, is not being made from
a food (flesh). Further, the process used to make the product goes through
a stage where the product is so "unfit" that it is not edible by
man nor dog and as such becomes a new entity.
Rabbis holding this view even accept pork gelatin. Most gelatin
desserts with a generic "K" follow this ruling. Other rabbis only permit gelatin from beef bones and
hides and not pork. Other rabbis will only accept "India dry
bones" as a source of beef gelatin. These bones, found naturally in
India (because of the Hindu custom of not using cattle) are aged for over
a year and are "dry as wood"; additional religious laws exist
for permitting these materials. However,
to repeat, none of these products are accepted by the
"mainstream" kosher or halal supervisions and thus products with
these gelatins are not accepted by a significant part of the kosher and
halal community. Biotechnology Rabbis, imams, and mullahs currently accept products
made by simple genetic engineering, e.g., chymosin (rennin) was accepted
by the rabbis about a half year before it was accepted by the FDA! The production conditions in the fermentors must still be
kosher or halal, i.e., the ingredients and the fermentor and any
subsequent processing must use kosher or halal equipment and ingredients
of the appropriate status. A product produced in a dairy medium would be
dairy. We believe that the rabbis may soon approve porcine lipase made
through biotechnology, if all the other conditions are kosher, but the
Muslim community is still considering this issue and a final ruling has
not been established. (Any product produced by cattle by excretion in the
milk would be dairy!) The religious leaders of both communities have not
yet determined the status of more complex genetic manipulations. Federal and State Regulations Making a claim of kosher on a product is a
"legal" claim. 21CFR101.29 has a paragraph indicating that such
a claim must be appropriate and approximately 20 states, some counties,
and some cities have laws specifically regulating the claim of
"kosher." Many of these laws refer to "Orthodox Hebrew
Practice" or some variant of this term and their legality in the
1990s is subject to further court interpretation. (Note recent court
rulings in New Jersey and Baltimore.) New York State probably has the most extensive set of
kosher laws, including a requirement to register kosher products with the
Kosher Enforcement Bureau of the Department of Agriculture and Markets (55
Hanson Pl, Brooklyn, NY 11217). However, the laws in New Jersey -- having
been written after the state's original laws were declared
unconstitutional by the state supreme court -- probably have the clearest
focus and, it is hoped, no Constitutional issue. They focus specifically
on "consumer right to know issues" and "truth in
labeling." They avoid having the state of New Jersey define kosher.
Rather the rabbis providing supervision declare the information that
consumers need to make an informed decision. We hope that a similar
approach will be adopted by the other states, particularly New York State
and that all of the states will extend the same protection to food
products produced with halal certification. Kosher and Allergies Although it is helpful for many consumers to use the
kosher markings as a guideline for determining whether products might meet
their special needs, there are also limitations that the particularly
sensitive consumer needs to be aware of. With respect to all kosher products, two important limitations need to be recognized:
Products that one might expect to be made in a dairy
plant, e.g., pareve substitutes for dairy products and some other liquids
like teas and fruit juices may be produced in plants that have been
kosherized, but may not meet a very critical allergy standard. Another
product that can be problematic is chocolate: many plants make both milk
chocolate and pareve chocolate. Getting every last trace of dairy out of
the pareve chocolate can be difficult. Dairy and Meat Equipment: The product was produced on
a dairy or meat line, without any equipment kosherization. However, there
are no intentionally added dairy or meat ingredients. The product is
considered pareve with some use restrictions in a kosher home. Fish: In a few instances where pareve or dairy
products contain small amounts of fish (e.g., anchovies in Worcestershire
sauce), this ingredient MAY be marked as part of the kosher supervision
symbol. Many certifications will not specifically mark this. For Passover, there is some dispute about
"derivatives" of both chometz and kitnyos materials and a few
rabbis permit items like corn syrup, soybean oil, peanut oil, and
similarly derived materials from these extensions. In general, "proteinaeous"
part of these materials are not used. Thus, people with allergies to these
items could purchase these special Passover products from supervision
agencies that do NOT permit "kitnyos" derivatives.
With respect to "equipment kosherization": supervising
rabbis tend to be very strict about the clean-up of the prohibited grains
(wheat, rye, oats, barley, and spelt) so these should come closest to
meeting potential allergy concerns, but may not be as critical with
respect to the extended prohibition. Consumers should not assume that kosher markings
ensure the absence of trace amounts of the ingredient to which they are
allergic. How thorough can the dairy line be blocked out? The
cleaning probably should go beyond any interlock that exists to lock out
the incoming dairy proteins to assure that cross-contamination does not
occur. Currently what is acceptable for kosher may not meet the needs of
allergic consumers. Is the dairy powder dust in the air sufficient to
cause problems? A company might want to consider putting a special marking
on kosher pareve chocolates produced on lines that also produce dairy
products to indicate that these are religiously pareve, but not
sufficiently devoid of dairy allergens for very allergic consumers.
Furthermore, they may also want to consider checking the chocolate using
one of the modern antibody or similar types of tests. For example, regular
M&Ms are marked as containing "peanuts" in order to alert
people who are very allergic to peanuts, even though the product does not
contain peanuts, because common equipment (although cleaned between
product runs) is used for both products. Kosher Poultry This section will simply highlight some differences
when animals are slaughtered for kosher or halal use. Animals for kosher slaughter, like regular animals,
may either be raised on contract -- so that the slaughtering company
controls the supply, or may be purchased on the open market, in which case
the company does not control the stock prior to processing. If the company is in control of the live animals, two
issues are important. The first is the issue of injections. The animals
may receive injections but they must be done in such a way as not to be
classified rabbinically as a “puncture” that would prevent the animal
from surviving for a year. (These standards are rabbinical and should not
be thought of in terms of modern scientific discussions.) Of particular
concern are injections to the neck region, such as may be used for hormone
treatments. Thus, although
not religiously required, many of the kosher producers tend not to use
hormones or antibiotics requiring shots. A second issue with the live animal is the feed --
interestingly, the two issues that are of concern are feeds that contain
milk and meat -- but not those with non-kosher ingredients, and those
concerning “baked” chometz. In
the latter case, the issue is the processing of poultry during the 4 (at
most) intermediate days of Passover. The shochet, using a very sharp knife, called a “chalef” to sever the windpipe, the jugulars, and the carotids. The shochet then inspects the animals to check that the cut was made properly and checks his knife to make sure it is still sharp, if not the animal will be rejected. Generally, the shochets work for one hour and then are off for one hour. Prior to “shechting,” the shochet will say a prayer asking for forgiveness. In order to be a shochet, the man must be a pious, observant Jew and must past a test on both his religious knowledge about the requirements for shechting and on his practical ability to carry out the job correctly. The work of the individual shochets is not monitored, so that there is no pressure on the shochet to keep a specific pace. At some point, either immediately before or after
USDA inspection, the bodek (internal organ inspectors) will thoroughly
examine all parts of the animal. The bodek looks particularly closely at
the lungs. In order to run a kosher plant, additional kosher supervisers are needed to oversea the complexities of maintaining a kosher plant. In addition, because plants may be isolated, provisions for housing, feeding (strictly kosher!) and providing for the religious personnel’s relgious needs (e.g., prayers three times a day) must be met, generally on site. Scheduling of the plant must be done so as to permit religious personnel to return to their home city in time for the Sabbath (every Friday) and for other religious holidays. Obviously kosher operations will not occur on Jewish religious holidays. References and Additional Readings Chaudry, M.M. 1992.
