FACT: Some of the proteins in edible insects, like crickets and mealworms, are similar to those found in crustaceans (e.g. crab, shrimp, lobster). This is why people with a crustacean allergy can have allergic reactions to edible insects, which are becoming more widely available as snacks or as a source of protein in certain foods. Talk to your allergist about any concerns before consuming edible insects or foods containing them.
In addition to crustaceans, there are other allergies to talk to your allergist about which may be relevant to safely consuming crickets. These include other insect allergies such as cockroach allergy as well as house dust mite allergy.
Keep in mind that edible insects are not considered a priority food allergen and are not subject to the enhanced allergen labelling requirements. However, the list of ingredients must identify them whenever they’re a primary ingredient in a pre-packaged food. Always read the label when you purchase a product and call the manufacturer if you have any questions before consuming the product.
