An article published by Dr Scott Russell, an extension poultry scientist, said the white spots could be bacteria called Lactobacilli or yeast cells.
Woody white patches on raw chicken that's been frozen and thawed are signs of freezer burn. In this case, it's safe to eat, but for the best taste, trim away and discard the white parts.
Essentially it's a protein - but blood serum is the substance. All meats including poultry and fish ooze out this stuff especially during cooking, the heat causes it to come out of the meat /muscle fibres. It turns white very much how egg white turns white when exposed to heat.
The white dried patches indicate freezer burn. When meat and poultry have been frozen for an extended period of time or have not been wrapped and sealed properly, this will occur. The product remains safe to eat, but the areas with freezer burn will be dried out and tasteless and can be trimmed away if desired.

Chickens sick with salmonella will be weak, lethargic, have purplish combs and wattles, a decreased appetite and increased thirst. Plus you will see distinct white, sulfur yellow or green diarrhea. In some cases, joints might be swollen and blindness might occur from swelling in the eyes.
The white stringy parts in chicken breasts are tendons.
The tough tendons are located along the side of chicken tenderloins. Tendons are strong connective tissue made primarily of collagen and they attach the meat to the bone.
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.”
These white dots that appear inside the meat are tyrosine crystals. So what is tyrosine? This is a non-essential amino acid (chemical units of the body that are formed by proteins) in mammals that is produced from another amino acid called phenylalanine.
White meat refers to the breast and wing portions of the chicken (tenders or tenderloin meat is a section of the breast, so this is also white meat). This cut of protein tends to be incredibly lean and has a notable pale (white) color when cooked without seasoning.
Fresh, raw chicken should have a pale pink, peachy color. As it begins to go bad, the color fades to a shade of grey. If the color of your raw chicken begins looking duller, cook it immediately and do not wait any longer to use it. Check to see if any fatty parts have turned yellow or bright yellow, too.
Eating bad chicken can lead to food poisoning, with symptoms such as nausea, vomiting, diarrhea, abdominal cramps, and fever. In some cases, it can also lead to more serious health complications or even death. It is important to properly store and cook chicken to ensure safety and avoid these risks.
How long does chicken last in the refrigerator? Surprisingly or not, raw chicken, whether it's whole or cut into parts (breasts, thighs, drumsticks, wings), lasts in the fridge between one to two days, according to the Cold Food Storage Chart from FoodSafety.gov, one of the federal consumer resources for food safety.
Storing Chicken in the Fridge
No need to stash it in the freezer — it's OK to store raw chicken (whole or in pieces) for 1–2 days in the fridge. If you have leftovers that include cooked chicken, you can expect those to last in the refrigerator for 3–4 days.
A use-by date on food is about safety. This is the most important date to remember. Never eat food after the use-by date, even if it looks and smells ok, as it could make you very ill.
What Is the Foam? There is no appetizing way to say this, but that foam is made of coagulated chicken proteins. "It is known as scum, not the most pleasant name. It is considered an impurity when in a stock and consists of coagulated proteins coming from any residual meat on the bones.
The short answer: Yes, cooking can kill Salmonella. Depending on the type of food, the Centers for Disease Control and Prevention recommend cooking food to a temperature between 145 degrees F and 165 degrees F to kill Salmonella.
Salmonella bacteria can be completely eradicated in meat and poultry through exposure to high temperatures, such as cooking meat and poultry to a minimum internal temperature of 165° F.
If it looks OK and smells OK but feels extra slimy, sticky or dry from freezer burn, it's time to say goodbye. “Raw chicken can have a somewhat slimy feel to it, but if it has a slimy feel after it is rinsed off and patted dried, it's no longer good,” Danielson said.
This occurs in areas where CO2 snow is used and a source of chicken juice or blood is present. Sometimes, CO2 snow is used to chill poultry parts during marination. An anaerobic environment prevents the growth of normal spoilage bacteria but allows for the growth of Lactobacilli.
"Cooked chicken will start to appear gray or greenish, and have a softer or slimier texture when it starts to go bad; as well as a foul smell. Cooked chicken may also develop mold or white patches on it, which indicates it has gone bad," says Katie Tomaschko, M.S., RDN.
If chicken that cooked white begins to look grey, it is no longer safe to eat. Look for mold. Mold is one of the most obvious signs of rotten, decaying, bad chicken. If green, or black fuzz, or any organic growth of any kind has begun to form on the chicken, it has gone very bad and should be discarded immediately.
