You should avoid eating oysters in Mazatlan
Mexico's Coepriss issued a sanitary ban on bivalve mollusks due to the presence of red tide in Mazatlan.
If you were planning to go to get your favorite seafood, go, but don't eat any mollusks. The Ministry of Health, through the State Commission for the Protection against Sanitary Risks of Sinaloa (Coepriss), declared a sanitary ban on the extraction, storage, commercialization, and consumption of bivalves mollusks in the bay area of this port city, due to the presence of red tide.
It will be better not to consume oysters, clams, mussels, mule's foot, scallops, and snails, coming from this area or that are in wet storage. The ban is temporary and precautionary, and applies to the extraction, wet storage, marketing, and consumption of bivalve mollusks, and is directed to retailers, restaurants, and traders of bivalve mollusks.
The red tide caused a higher than normal concentration of marine biotoxins in the mollusks. The restriction does not apply to products such as fish, crabs, shrimp, or lobster, and in case of any symptoms of intoxication, affected persons should not self-medicate and should go to the nearest health center.
