he FDA last week that shellfish originating from growing areas in Netarts Bay and Tillamook Bay, Oregon, may be contaminated with the toxins that cause paralytic shellfish poisoning, or PSP. The administration is advising consumers to avoid eating oysters and clams from the region, including calling on restaurants and food retailers to dispose of them. The contamination has been found in oysters and bay clams distributed in Arizona, California, Colorado, Hawaii, Nevada, New York, Oregon and Washington.
As of May 30, the FDA had not reported any illnesses or deaths from the poisoning. Here’s what to know about paralytic shellfish poisoning. Paralytic shellfish poisoning originates from paralytic shellfish toxin, a naturally occurring biotoxin that is produced in some species of microscopic algae.
When molluscan shellfish, such as clams, mussels, oysters, geoduck, and scallops, consume the toxin in algae, they can accumulate the poison. While some species are able to quickly rid themselves of the toxins, others take longer to cleanse it from their systems. The toxin can be passed on to humans through eating shellfish and crabs, which might also become toxic when they feed on infected shellfish.
Symptoms of PSP can occur within 30 minutes of consuming contaminated seafood and can range from tingling of the lips, mouth, and tongue, to respiratory paralysis and may include these other symptoms: numbness of arms and legs, “pins and needles” sensation, weakness, loss of muscle.
