Went to use nacho Doritos dip open in fridge , tipped in bowl and spread some on meat, suddenly realised another one in fridge , asked ds who said that was his he forgot about, been in fridge 2-3 weeks ,and not the one we opened and used yesterday. I had already washed out the jar and quickly washed out bowl but I think i ate the tiniest bit off my finger when dishing out , google bring up all sorts of things , says eat within 2 days on jar.
