Father, I have sinned, for I ate medium rare steak twice in the last two months, had sushi (salmon, not tuna, to avoid mercury), and also drank more than 12 ounces of coffee on one occasion, perhaps two. I also had a taster of beer recently and a bite of shrimp ceviche.
They tell pregnant women not to eat sushi, uncooked seafoods (ceviche! smoked salmon! sob!), medium rare steak, hummus, deli meats, among others, but no one said a damn thing about moldy tortillas, did they? I had a couple of tortillas that tasted fine, only to check the package later and realize some of them were growing mold. I then proceeded to have stomach problems for the next 24 hours.
Of course the culprit would not be anything listed in the first paragraph, but something like flour tortillas. Irony.
