Taken from the Cal. Fish & Game website: 
"Recreational Fisheries for Dungeness Crab and Rock Crab

• The recreational fishery for all rock crab species is open statewide. North of Bodega Bay, Sonoma County, the California Department of Public Health (CDPH) advises that consumers not eat the viscera (internal organs, also known as "butter" or "guts") of crabs. The viscera usually contain much higher levels of domoic acid than crab body meat. Review recent changes to recreational crab fishing regulations.
• The recreational Dungeness crab fishery is currently open statewide, and the California Department of Public Health (CDPH) has lifted its Dungeness crab consumption advisory statewide. However, CDPH still recommends not eating the viscera (internal organs, also know as "butter" or guts) of Dungeness crab as a precaution. The viscera usually contain much higher levels of domoic acid than crab body meat. Review recent changes to recreational crab fishing regulations."
