Shellfish harvesting areas near public beaches in Washington state have been closed to recreational and sport harvest due to the dangers of fecal contamination and marine biotoxins. Commercial harvesting may also be restricted based on selective testing, according to state health authorities. In addition, some areas have been listed as “threatened” meaning they are reaching the cut-off limit of what is acceptable in terms of water pollution. “If water quality in the threatened shellfish areas gets worse we’ll have to restrict or close harvesting there,” Bob Woolrich, Growing Area Section Manager said in a statement. “Having an area listed as ‘threatened’ is a signal to communities to identify and correct pollution problems.” In some areas, pollution-mitigation efforts are underway. … [Read more...]
Warning: California Department of Health Says Not to Eat Shellfish from Del Norte County California
The California Department of Health is telling consumers not to eat shellfish that are recreationally harvested from Del Norte County in California. The warning does not apply to commercially sold clams, mussels, scallops, or oysters from approved sources. These commercially harvested shellfish are subject to frequent mandatory testing by the state government.

California Warns Consumers to Avoid Seafood Harvested in Northern Channel Islands
The California Department of Public Health (CDPH) is warning consumers to not eat recreationally harvested mussels and clams, commercially or recreationally caught anchovy and sardines, or internal organs of commercially or recreationally caught crab and lobster from the northern Channel Islands.

Vibrio in Shellfish Sicken 30 in Washington State
According to the Washington State Department of Health, Vibrio in shellfish have caused 30 confirmed illnesses in Washington this summer. The presence of the bacteria has closed three commercial growing areas, including Totten Inlet near Olympic, North Bay, and Dabob Bay in north Hood Canal for the rest of the summer. Vibriosis, the illness caused by the bacteria Vibrio parahaemolyticus, is caused by eating raw or undercooked oysters. Despite the typical recommendation of cooking shellfish until they open, that is not enough to destroy Vibrio. To be safe, shellfish should be cooked to an internal temperature of 145 degrees F for 15 seconds. In addition, rinsing cooked oysters in seawater can re-contaminate them. And, some pathogens can't be "cooked out" of shellfish. Some biotoxins can … [Read more...]
