Black bone syndrome (BBS) affects poultry industry, and it is caused by the darkening of the tissue adjacent to the bone due to leak age of bone marrow contents during cooking.
Color. Changes in color, just like with raw or cooked chicken, is an indication that the chicken has expired. Unlike the raw or cooked chicken, if the chicken has become faded, or paler in color than when it was frozen or, on the opposite end, has darkened—it is no longer safe to consume.
If there is no congealed blood, the bruise is of no concern. If there was congealed blood and cuts were not made before salting in the area where the blood is congealed, the bruised section must now be cut away.
Fresh, raw chicken is pink and fleshy in color; if the chicken has gone bad it will be discolored and take on a dull, grayish cast. “Signs of food spoilage are pretty universal,” White says. “Any foul odor, discoloration or foreign substances on your chicken would be grounds for tossing.”
Dark meat has long been enjoyed as an indulgent alternative to white meat. The richer flavour and higher moisture content of dark meat makes it the perfect choice for many recipes, including such decadent classics as fried chicken or coq au vin.
Since their bones have not calcified completely, pigment from the bone marrow can seep through the porous bones. When the chicken is cooked, the pigment turns dark. Freezing can also contribute to this seepage. It's perfectly safe to eat chicken meat that turns dark near the bone during cooking.
Research suggests that the dark meat of black chicken breeds like the Kadaknath provides a rich source of carnosine. Carnosine is a protein-building compound that has antioxidant properties, so eating black chicken meat may be a healthier choice than white meat.
Fresh raw chicken should have a light pink hue to it with fat parts being white. If the color fades, it's looking yellow or gray in color, has mold or a different color tinge, it's no longer safe to eat. When purchasing frozen chicken, check for signs of thawing and refreezing.
Pink or bloody-looking poultry is often not your fault, and, in fact, may be safe to eat, as long as it has reached the correct internal temperature (more on that below).
The liquid contained in the mass of a chicken expands during freezing, including the bone marrow. The dark marrow can push through the bone's surface as it expands. The bones and meat adjacent to them become stained, and will remain a deep red/purple color regardless of the final internal temperature of cooked chicken.
Common indications of a sick chicken include: hiding, inactivity, pale comb or wattles, unusual droppings, unusual posture, lethargy, lack of appetite and reduced egg production- all indications that closer observation is needed.

How Do These All-Black Chickens Get Their Color? Leif Andersson, a geneticist at Uppsala University in Sweden, told National Geographic that the black color is the result of a genetic mutation called fibromelanosis, which can be traced back to a single bird from hundreds or even thousands of years ago.
The black spots are just coagulated blood. There is nothing unsafe about eating the meat. You can scrape out the blood/dark spot if you desire. Many Americans and some other nationalities are adverse to eating the dark meat of chicken.
At times however, a bruise with a blackish, bluish appearance can still be found by the consumer. Ideally this should be removed prior to cooking the chicken, and the remainder of the chicken may be eaten.
How Long Will Raw Chicken Stay Good in the Fridge? One to two days maximum. That's according to the USDA and U.S. Food and Drug Administration, and applies to raw chicken regardless of if it's whole; in pieces such as breasts, thighs, drumsticks, and wings; or ground.
When fresh, raw chicken has a pink, fleshy color. As it starts to spoil, the color fades to grey. If the color of the chicken begins to look duller, you should use it soon before it goes bad. Once it looks more grey than pink, it is already too late.
Myth: Washing or rinsing raw chicken or turkey before cooking removes harmful bacteria. Fact: Thoroughly cooking chicken and turkey to 165°F is the best way to kill harmful bacteria such as Campylobacter and Salmonella.
The birds' black color occurs as a result of excess pigmentation of the tissues, caused by a genetic condition known as fibromelanosis. Fibromelanosis is also found in some other black or blue-skinned chicken breeds, such as the Silkie. The roosters weigh 2–2.5 kg (4.4–5.5 lb) and the hens 1.5–2 kg (3.3–4.4 lb).
According to the American Institute for Cancer Research (AICR), charring meat, poultry and fish can lead to the formation of heterocyclic amines (HCAs), carcinogens that may cause cancer.
Human bodies need a certain amount of fat every day for regular healthy functions. Dark meat chicken contains twice as much healthy unsaturated fat as light meat chicken — although it does also contain twice as much saturated fat, the number is still small.
