Unless food is prepared in Walter White's 99.1% pure meth superlab (Breaking Bad reference, anyone? Ok, I'll continue.), there is a good chance some contaminants are going to be in them. I'm of the mindset that if I turn the other way and pretend they're not there, I won't notice. Noticing would be the worst. Ugh. But apparently the US Food and Drug Administration deems these to be acceptable. I can see how they could get in there, BUT WHY PUBLICIZE IT! LET US BE NAIVE AND NOT KNOW WE'RE EATING UP TO 19 MAGGOTS PER 100 GRAMS OF CANNED MUSHROOMS! But seriously, gross.
