Raw oysters and clams from 2 B.C. inlets recalled

Some oysters and clams recently harvested in two British Columbia inlets may contain paralytic shellfish toxins, and the lots have been voluntarily recalled by shellfish processors.

A health hazard alert issued Friday by the Canadian Food Inspection Agency says the shellfish were sold primarily to restaurants and other institutional-type businesses, but may also have been sold at retail seafood counters.

The recall applies to clams and oysters harvested on Tuesday, Aug. 13, from Effingham Inlet and Useless Inlet in B.C., and were packaged or distributed by Albion Fisheries, Pacific Rim Shellfish, or Clear Bay Fisheries Inc.

The products have been distributed in B.C. and Alberta, but may also have been sent to other provinces.

No reports of Paralytic Shellfish Poisoning (PSP) have been received. The CFIA says symptoms of PSP include "tingling and numbness of the lips, tongue, hands and feet, and difficulty swallowing."

"In severe situations, this can proceed to difficulty walking, muscle paralysis, respiratory paralysis and death in as quickly as 12 hours," the CFIA says.
