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.
I had a question about the length of time you can keep cooked meat in the refrigerator. I thought it was 3-4 days at most. But when I shop at Whole Foods and buy their bucket of chicken every week, the label says the following: As you can see, the sell by date is actually 5 days after the day they cooked it.
