What's for dinner tonight? There's a good chance it's chicken -- now the number one species consumed by Americans. Interest in the safe handling and cooking of chicken is reflected in thousands of calls to the USDA Meat and Poultry Hotline, second only to turkey in number of specific inquiries. The following information answers many of the questions these callers have asked about chicken.
All chickens found in retail stores are either inspected by USDA or by state systems which have standards equivalent to the Federal government. Each chicken and its internal organs are inspected for signs of disease. The "Inspected for wholesomeness by the U.S. Department of Agriculture" seal insures the chicken is free from visible signs of disease.
Inspection is mandatory but grading is voluntary. Chickens are graded according to USDA Agricultural Marketing Service regulations and standards for meatiness, appearance and freedom from defects. Grade A chickens have plump, meaty bodies and clean skin, free of bruises, broken bones, feathers, cuts and discoloration.
Fresh or Frozen
The term fresh on a poultry label refers to any raw poultry product that has never been below 26 °F. Raw poultry held at 0 °F or below must be labeled frozen or previously frozen. No specific labeling is required on raw poultry stored at temperatures between 0-25 °F.
Dating of Chicken Products
Product dating is not required by Federal regulations, but many stores and processors voluntarily date packages of chicken or chicken products. If a calendar date is shown, immediately adjacent to the date there must be a phrase explaining the meaning of that date such as sell by or use before.
The use-by date is for quality assurance; after the date, peak quality begins to lessen but the product may still be used. It's always best to buy a product before the date expires. If a use-by date expires while the chicken is frozen, the food can still be used.
Hormones & Antibiotics
No hormones are used in the raising of chickens.
Antibiotics may be given to prevent disease and increase feed efficiency. A "withdrawal" period is required from the time antibiotics are administered before the bird can be slaughtered. This ensures that no residues are present in the bird's system. FSIS randomly samples poultry at slaughter and tests for residues. Data from this monitoring program have shown a very low percentage of residue violations.
Additives are not allowed on fresh chicken. If chicken is processed, however, additives such as MSG, salt, or sodium erythorbate may be added but must be listed on the label.
Foodborne Organisms Associated with Chicken
As on any perishable meat, fish or poultry, bacteria can be found on raw or undercooked chicken. They multiply rapidly at temperatures between 40 °F and 140 °F (out of refrigeration and before thorough cooking occurs). Freezing doesn't kill bacteria but they are destroyed by thorough cooking of any food to 160 °F.
USDA's Food Safety and Inspection Service has a zero tolerance for bacteria in cooked and ready-to-eat products such as chicken franks or lunch meat that can be eaten without further cooking.
Most foodborne illness outbreaks are a result of contamination from food handlers. Sanitary food handling and proper cooking and refrigeration should prevent foodborne illnesses.
Bacteria must be consumed on food to cause illness. They cannot enter the body through a skin cut. However, raw poultry must be handled carefully to prevent cross-contamination. This can occur if raw poultry or its juices contact cooked food or foods that will be eaten raw such as salad. An example of this is chopping tomatoes on an unwashed cutting board just after cutting raw chicken on it.
Following are some bacteria associated with chicken:
Rinsing or Soaking Chicken
It is not necessary to wash raw chicken. Any bacteria which might be present are destroyed by cooking.
Liquid in Package
Many people think the pink liquid in packaged fresh chicken is blood, but it is mostly water which was absorbed by the chicken during the chilling process. Blood is removed from poultry during slaughter and only a small amount remains in the muscle tissue. An improperly bled chicken would have cherry red skin and is condemned at the plant.
How to Handle Chicken Safely
FSIS recommends three ways to defrost chicken: in the refrigerator, in cold water and in the microwave. Never defrost chicken on the counter or in other locations. It's best to plan ahead for slow, safe thawing in the refrigerator. Boneless chicken breasts will usually defrost overnight. Bone-in parts and whole chickens may take 1 to 2 days or longer. Once the raw chicken defrosts, it can be kept in the refrigerator an additional day or two before cooking. During this time, if chicken defrosted in the refrigerator is not used, it can safely be refrozen without cooking first.
Chicken may be defrosted in cold water in its airtight packaging or in a leak proof bag. Submerge the bird or cut-up parts in cold water, changing the water every 30 minutes to be sure it stays cold. A whole (3 to 4-pound) broiler fryer or package of parts should defrost in 2 to 3 hours. A 1-pound package of boneless breasts will defrost in an hour or less.
Chicken defrosted in the microwave should be cooked immediately after thawing because some areas of the food may become warm and begin to cook during microwaving. Holding partially cooked food is not recommended because any bacteria present wouldn't have been destroyed. Foods defrosted in the microwave or by the cold water method should be cooked before refreezing.
Do not cook frozen chicken in the microwave or in a slow cooker. However, chicken can be cooked from the frozen state in the oven or on the stove. The cooking time may be about 50% longer.
The Hotline does not recommend buying retail-stuffed fresh whole chicken because of the highly perishable nature of a previously stuffed item. Consumers should not pre-stuff whole chicken to cook at a later time. Chicken can be stuffed immediately before cooking. Some USDA-inspected frozen stuffed whole poultry MUST be cooked from the frozen state to ensure a safely cooked product. Follow preparation directions on the label.
Chicken may be marinated in the refrigerator up to 2 days. Boil used marinade before brushing on cooked chicken. Discard any uncooked leftover marinade.
FSIS recommends cooking whole chicken to 180 °F as measured in the thigh using a food thermometer. For approximate cooking times to use in meal planning, see the following chart compiled from various resources.
+ Unstuffed. If stuffed, add 15 to 30 minutes additional time.
* Indirect method using drip pan.
Never brown or partially cook chicken to refrigerate and finish cooking later because any bacteria present wouldn't have been destroyed. It is safe to partially pre-cook or microwave chicken immediately before transferring it to the hot grill to finish cooking.
Color of Skin
Chicken skin color varies from cream-colored to yellow. Skin color is a result of the type of feed eaten by the chicken, not a measure of nutritional value, flavor, tenderness or fat content. Color preferences vary in different sections of the country, so growers use the type of feed which produces the desired color.
Darkening around bones occurs primarily in young broiler-fryers. Since their bones have not calcified completely, pigment from the bone marrow can seep through the porous bones. Freezing can also contribute to this seepage. When the chicken is cooked, the pigment turns dark. It's perfectly safe to eat chicken meat that turns dark during cooking.
When chicken has reached 180 °F as measured using a food thermometer, it should be safe to eat. The pink color in safely cooked chicken is due to the hemoglobin in tissues which can form a heat-stable color. Smoking or grilling may also cause this reaction, which occurs more in young birds.
Color of Giblets
Giblet color can vary, especially in the liver, from mahogany to yellow. The type of feed, the chicken's metabolism and its breed can account for the variation in color. If the liver is green, do not eat it. This is due to bile retention. However, the chicken meat should be safe to eat.
Chickens may seem to have more fatty deposits or contain a larger "fat pad" than in the past. This is because broiler fryer chickens have been bred to grow very rapidly to supply the demand for more chicken. Feed that is not converted into muscle tissue (meat) is metabolized into fat. However, the fat is not "marbled" into the meat as is beef or other red meat, and can be easily removed. Geneticists are researching ways to eliminate the excess fat.
Food-grade trisodium phosphate (TSP) has been approved by FSIS for use in poultry slaughter as an antimicrobial agent. When immersed in and/or sprayed in a dilute solution on chickens, it can significantly reduce bacteria levels. TSP is "generally recognized as safe" (GRAS) by the FDA, and has been safely used for years, particularly in processed cheese.
Irradiation of Poultry
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. Irradiation at 1.5 to 3.0 kilo Gray, the smallest, most practical "dose," would eliminate more than 99 percent of Salmonellae organisms on the treated poultry.
Packages of irradiated chicken are easily recognizable at the store because they must carry the international radura symbol along with the statement, "treated with irradiation" or "treated by irradiation."
Since product dates aren't a guide for safe use of a product, how long can the consumer store the food and still use it at top quality? Follow these tips:
