DIY Personal Domoic Acid Testing of Crabs

May 5, 2016

Question: Is there any kind of Domoic acid test kit available that a consumer can use to test his/her own crabs? I would think there would be a lot of interest in this. I love to catch and eat crabs but also hate risking getting sick! (Bob W.)

Answer: If you do a google search you will find some kits that state they will detect Domoic acid toxins in shellfish, marine algae and water samples. However, if you only eat crabs harvested from areas where the California Department of Public Health (CDPH) has deemed safe following extensive testing of both the crab meat and viscera to determine they are below action levels, those crabs should be safe to consume. Toxins are known to collect and concentrate specifically in the green “crab butter” that some people enjoy. To check for current health warnings on the consumption of crabs and other shellfish, I suggest you call CDPH’s shellfish hotline at (800) 553-4133. This information is always up to date and available via a recorded message 24/7.
