So going back to that fish smell, what could cause an allergic reaction is not the smell itself but fish particles, very small pieces of fish protein floating in the air. Does this mean that if you have a severe food allergy, you should run for cover whenever you sense even just a scent of the food? Therefore, if you happen to smell fish from a fish market or restaurant several blocks away, chances are that you are not getting a waft of enough of the fish protein. Unfortunately, it is possible to take all of these proper steps and still succumb to a severe food allergy. But cases like this should raise more awareness of food allergies and how to properly deal with them.
