With a reaction to crayfish, should crabmeat be avoided?

Crayfish, crabs, shrimps, and lobsters are all crustaceans. With individual results for any of these foods go by that result. If you get a positive result for 1 or 2 of them but the others are not covered due to the size of test you have chosen, then it is best to initially stay away from all of the listed foods you don’t have a result for. This is because they share some of the same proteins. Once your symptoms have settled down, try introducing them one at a time into your diet. If you don’t feel any adverse effects, then include them in your rotation diet.
