If you think you became sick from consuming a recalled product, call your doctor. Check to see if you have recalled products in your home or establishment. Recalled products should be thrown out or returned to the location where they were purchased. Paralytic shellfish toxins are a group of natural toxins that sometimes accumulate in bivalve shellfish that include oysters, clams, scallops, mussels and cockles. Non-bivalve shellfish, such as whelks, can also accumulate Paralytic Shellfish Poisoning (PSP) toxins. These toxins can cause Paralytic Shellfish Poisoning (PSP) if consumed. Symptoms of Paralytic Shellfish Poisoning (PSP) include tingling and numbness of the lips, tongue, hands and feet, and difficulty swallowing with an onset of a few minutes and up to 10 hours after consumption. In severe situations, this can proceed to difficulty walking, muscle paralysis, respiratory paralysis and death.
