Ok so I just had this dish agua chile for the first time at my girlfriend's families house. It is basically a type of ceviche in which they slice the shrimp in half and soak one half of the slice with a blend of chiles and lime. Now what scared me about this dish was that the shrimp only sat in the lime mixture for 5 minutes before it was served, and only half of the fish was covered. I have no problem eating shrimp ceviche once it turns pink, nor eating sweet shrimp sushi, yet this had me hesitant. The shrimp was grey. For some reason I always thought that you should never eat raw shrimp.
so my question is that is it safe to eat raw shrimp from mexico in which only one half of the shrimp have been cured in lime juice for 5 minutes. They all looked at me like i was crazy when I wanted to wait until it started to turn pink.
