Or it might be the prep/cooking/storing conditions. The sickest I ever got was at a flea market where this Mexican lady used to sell tacos and meat pies. She made them in the morning and stored them in a styrofoam cooler all day.
I use to eat the street vender tacos and tamales in Juarez, don't know what was in them but they were spicy and good...never an issue with the tummy
