Sometimes when I buy lunch meat cuts, from the supermarket, they quickly get slimy on the outside. Regardless of the date which is indicated by the sticker.
I perform taste, smell, and visual checks for discoloration, but the cuts of meat seem to pass all those criteria.
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.
