Turkey is a large, widely domesticated North American bird with white plumage and a bare, wattled head and neck. The name turkey was originally applied to an African bird now known as the guinea fowl, which was believed to have originated in Turkey. When the Europeans came upon the American turkey, they thought it was the same bird as the African guinea fowl, and so gave it the name turkey, although the two species are quite distinct.

Turkeys are fed a diet of mainly corn and soybean meal along with a supplement of vitamins and minerals. They grow to full maturity in about 4 to 5 months, depending on the desired market weight.

All turkeys found in retail stores are either inspected by the USDA or by State systems which have standards equivalent to the federal government. Each turkey and its internal organs are inspected for evidence of disease. The "Inspected for wholesomeness by the U.S. Department of Agriculture" seal ensures that it is wholesome, properly labeled and not adulterated.

Inspection, for wholesomeness, is mandatory but grading, for quality, is voluntary. If companies choose to have their poultry graded, they pay for this USDA service. Grade A is the highest quality and the only grade you are likely to see at the retail level. The grade shield for poultry may be found on the following ready-to-cook products, whether chilled or frozen: whole carcasses and parts, and other boneless and/or skinless poultry products. Grade A indicates that the poultry products are virtually free from defects such as bruises, discolorations, and feathers. Bone-in products will have no broken bones. For whole birds and parts with skin on, there will be no tears in the skin or exposed flesh that could dry out during cooking, and there will be a good covering of fat under the skin. Also, whole birds and parts will be fully fleshed and meaty.

NO HORMONES have been approved for use in turkeys. Antibiotics may be given to prevent disease and increase feed efficiency. In approving drugs for use in livestock and poultry, the Food and Drug Administration (FDA) and Food Safety and Inspection Service (FSIS) work together. FDA sets legal limits for drug residues in meat and poultry. FSIS enforces the limits FDA sets for drug residues.

A "withdrawal" period is required from the time antibiotics are administered before the bird can be slaughtered. This assures that no residues are present in the bird's system. FSIS randomly samples poultry at slaughter and tests for residues. Under the Federal meat and poultry inspection laws, any raw meat or poultry shown to contain residues above established tolerance levels is considered adulterated and must be condemned.

Additives are NOT allowed on fresh turkeys or those "minimally processed" (cut into parts). However, if turkeys are "processed" (injected with a basting solution, ground, canned, cured, smoked, dried or made into luncheon meats), additives such as MSG, salt, or sodium erythorbate may be added but must be listed on the label in descending order from largest to smallest amount of the ingredient.

Bone-in poultry products that are injected or marinated with a solution containing butter or other edible fat, broth, stock or water plus spices, flavor enhancers and other approved substances must be labeled as "basted" or "self-basted." The maximum added weight of approximately 3% solution before processing is included in the net weight on the label. The label must include a statement identifying the total quantity and common or usual name of all ingredients in the solution, e.g., "Injected with approximately 3% of a solution of _______ (list of ingredients)."

The term "fresh" may ONLY be placed on raw poultry that has never been below 26 °F. Poultry held at 0 °F or below must be labeled "frozen" or "previously frozen." No specific labeling is required on poultry between 0 and 26 °F.

This poultry label rule addresses a truth-in-labeling issue, not food safety, because most pathogenic bacteria do not multiply or multiply very slowly at normal refrigerator temperatures. The Agency concluded that the term "fresh" should not be used on the labeling of raw poultry products that have been chilled to the point they are hard to the touch.

The sex designation of "hen" (female) or "tom" (male) turkey is optional on the label, and is an indication of size. Toms are larger but both toms and hens should be equally tender.

Turkeys of either sex that are less than 8 months of age according to present regulations are considered "young" turkeys.

Product dating is not required by federal regulations. However, stores and processors may voluntarily date packages of turkey or turkey products. There are several types of dates:

• "Sell-By" date tells the store how long to display the product for sale. The product should be purchased before the date expires.
• "Best if Used By" date is recommended for best flavor or quality. It is not a purchase or safety date.
• "Use-By" date is the last date recommended for the use of the product while at peak quality. The date has been determined by the manufacturer of the product. A retailer may legally sell fresh or processed meat and poultry beyond the expiration date on the package as long as the product is wholesome.

FSIS requires safe handling instructions on packages of all raw or partially cooked turkey products (fresh and frozen) packaged and labeled in federally and State inspected plants or in retail stores and sold to consumers.

FSIS requires mandatory nutrition labeling for most multi-ingredient turkey products except the raw, single-ingredient products such as turkey breast. Voluntary nutrition labeling on the raw, single-ingredient turkey product is encouraged. As an alternative to providing nutrition information on the label, manufacturers of turkey products that fall in the voluntary nutrition labeling category also may provide nutrition information through point-of-purchase materials, such as pamphlets, wall posters, and videos.

In 1992, the USDA approved a rule to permit irradiation of raw, fresh or frozen packaged poultry to control certain common bacteria on raw poultry that can cause illness when poultry is undercooked or otherwise mishandled. The rule permits irradiation at 1.5 to 3.0 kiloGray, the smallest, most practical "dose" of irradiation for bacterial control with the goal of reducing the potential for foodborne illness.

Only small quantities of poultry have been treated. Packages of irradiated poultry would be easily recognizable at the store because they must carry the international radiation logo as well as the words "Treated with Irradiation" or "Treated by Irradiation."

Salmonella Enteritidis may be found in the intestinal tracts of livestock, poultry, dogs, cats and other warm-blooded animals, and inside fresh shell eggs. Salmonella infections occur when a person ingests live Salmonella bacteria, which then survive digestion and reproduce in the small intestine to numbers large enough to cause symptoms. This strain is only one of about 2,000 kinds of Salmonella bacteria. Thorough cooking destroys Salmonella bacteria.

Campylobacter jejuni is one of the most common causes of diarrheal illness in humans. It is found in the intestinal tracts of chickens, turkeys, cattle, swine, sheep, dogs, cats, rodents, monkeys, some wild birds and some asymptomatic humans. It has also been found in water, soil and sewage sludge. Avoiding cross contamination and proper cooking prevent infection by this bacterium.

Staphylococcus aureus can be carried on human skin, in infected cuts and pimples, in nasal passages and throats. They are spread by improper food handling. Always wash hands and utensils before preparing and serving food. Cooked foods that will not be served immediately should be refrigerated in shallow, covered containers. Perishable foods should not be left at room temperature more than 2 hours. Temperature abuse can allow the bacteria to grow and produce staphylococcal enterotoxin. Thorough cooking destroys staphylococcal bacterial cells, but staphylococcal enterotoxin is not destroyed by heat, refrigeration or freezing.

Listeria monocytogenes bacteria are common in the intestines of humans and animals and in milk, soil, leafy vegetables, and food processing environments. It can grow slowly at refrigerator temperatures. It is destroyed by cooking but a cooked product can be contaminated by poor personal hygiene. Observe "keep refrigerated" and "use-by dates" on labels.

• If dinner is picked up or delivered hot, the food must be kept at 140 °F or above if eating within 2 hours (1 hour in temperatures of 90 °F or above). It's not a good idea to try and keep the food hot longer than 2 hours.
• If holding the food longer than 2 hours, remove all stuffing from the turkey cavity, divide the turkey into smaller pieces and refrigerate everything in separate, shallow containers. Reheat thoroughly to 165 °F.
• If cooked and refrigerated, keep cold food cold. Refrigerate immediately upon arrival at home (always within 2 hours). Serve the meal within 2 days. Reheating a whole cooked turkey is NOT recommended. However, cooked turkeys with the USDA inspection seal on the packaging have been processed under controlled conditions. Follow package directions for reheating, and storing these products.

On cooked frozen turkey, look for the USDA inspection seal. It tells that the turkey was prepared in a USDA inspected plant. Read and follow package directions for thawing, reheating and storing. If there are no directions on the label, thaw the wrapped cooked frozen turkey on a tray in the refrigerator. The thawed turkey may be eaten cold. To eat it hot, slice breast meat. Legs and wings may be left whole. Reheat thoroughly to 165 °F.

Raw turkey skin color is off white to cream-colored. Under the skin the color ranges from a pink to a lavender blue depending on the amount of fat just under the skin.

If the turkey has reached a safe minimum internal temperature of 165 °F as measured with a food thermometer in the innermost part of the thigh and wing and the thickest part of the breast, it should be safe to eat. When there is a pink color in safely cooked turkey, it is due to the hemoglobin in tissues which can form a heat-stable color. This can also happen when smoking, grilling or oven cooking a turkey.
