PCBs get into wild salmon from the other fish they eat and into farmed salmon from their feed (which contains many of these same fish). The FDA has set the safe upper limit for PCBs at 2000 parts per billion (ppb). Farmed salmon averages 27 ppb, well below that limit.
To maximize the shelf life of cooked chicken for safety and quality, refrigerate the chicken in shallow airtight containers or wrap tightly with heavy-duty aluminum foil or plastic wrap. Properly stored, cooked chicken will last for 3 to 4 days in the refrigerator. To further extend the shelf life of cooked chicken, freeze it; freeze in covered airtight containers or heavy-duty freezer bags, or wrap tightly with heavy-duty aluminum foil or freezer wrap.
How long can you keep chicken in the fridge? Raw chicken: You'll need to either cook or freeze it fast. According to recommendations from the U.S. Food and Drug Administration, raw chicken will only keep in the refrigerator for about 1-2 days. (Same goes for turkey and other poultry.) If you store it in the freezer in a sealed, freezer-safe container or vacuum-sealed package, it should stay safe to thaw and eat for up to 9 months, in pieces, or up to 12 months, for a whole chicken. Cooked chicken: You have a little more time, but not much.
