Sometimes when I buy lunch meat cuts, from the supermarket, they quickly slimy on the outside. Regardless of the date which is indicated by the sticker.
I perform the taste, smell, and visual checks for discoloration; But the cuts of meat, seem to pass all those criterion.
Is this a sign that it's about to expire? Also, why does it get slimy.
FYI: This happens on Dietz BBQ chicken, and this other chicken cut I get from Costco.
