I have bought Bumble Bee Tuna for years and loved it, but the past few 3 or 4 months it's made me very sick. I don't know what it is, but there seems to be a piece in each can with a super strong taste that immediately makes me sick and feeling like I'm going to vomit and I have to brush my teeth a couple of times, floss and have a lemon or some vinegar to get the taste out of my mouth. It makes me start gagging. It's hard to describe the taste, but I've also noticed the cans are really strong smelling after I open them and I have to soak them overnight in soapy water to be able to throw them in the trash. Not sure if it's a tinny taste, but almost like a combination of tin and equivalent to the fish smell strength (but different flavor) of crab that's gone bad.
I just tried another can and had to throw away my entire salad and I ordered a dinner to be delivered. I'm returning the can to the store this time. It looks like the can says on it "best if used by 7/21/15" and it's 11/16/15 today. I don't know if the others have been past the best-used-by date. I'm feeling sick right now – stomach pains, light-headedness. I bit on a lemon and that at least helped get rid of the taste. If this is occurring a lot, it needs to be investigated.
