Canada – Advisory Alert Shellfish Vibro parahaemolyticus

CDC BC 

The BC Centre for Disease Control is reminding the public there’s a risk of illness associated with eating raw or undercooked bivalve shellfish such as oysters, clams, mussels, scallops, and cockles.

 Shellfish may accumulate bacteria(Vibrio parahaemolyticus), viruses (norovirus, hepatitis A), and toxins (paralytic shellfish poisoning, diarrhetic shellfish poisoning) or other impurities present in the water. Thorough cooking destroys bacteria and viruses, but does not destroy toxins.

 To date in 2012, five cases of locally-acquired Vibrio parahaemolyticus infection have been reported. In 2011, 42 cases of vibrio were reported. These illnesses have been linked to raw shellfish served in restaurants, bought at retail, or self-harvested in communities throughout the province including, Gibsons, Sechelt, Powell River, Ladysmith, Qualicum, Ucluelet, Gabriola Island, Cortes Island and Parksville.

In addition to individual cases, BC has also experienced outbreaks associated with shellfish. In 2010, an outbreak of norovirus from raw oysters affected over 30 people and in 2011 more than 60 people became ill after consuming cooked mussels contaminated with diarrhetic shellfish poisoning.

FSA – Move Away from Animal Testing for PSP

FSA

The Food Standards Agency’s shellfish monitoring programme has successfully completed a move away from tests using mice for the detection of paralytic shellfish poisoning (PSP) and lipophilic toxins in commercially harvested shellfish.

The phasing out of animal testing in the shellfish monitoring programme has been a long-term goal of the FSA. Without an approved alternative method available, tests on mice had previously been the most suitable way of detecting toxins in shellfish. However, the FSA and Cefas (Centre for Environment, Fisheries, and Aquaculture Science) have spent a number of years developing alternative testing methods that do not rely on mice.

Andrew Wadge, Chief Scientist at the Food Standards Agency, said: ‘This is a significant milestone in meeting the UK’s commitment to reduce the burden of animal testing and has been achieved after years of FSA-funded research.

‘PSP and lipophilic toxins can cause severe illness if people consume them, so it is important that our shellfish monitoring programme is as effective as possible at detecting them. In order to meet our commitment, we have had to ensure suitable alternative methods are introduced in all our statutory biotoxin testing.
