Food safety experts have issued warnings regarding the consumption of specific aquatic products to prevent poisoning and illness.

In early August, a seafood expert from Fuzhou, China, advised consumers to avoid low-quality freshwater snails from rivers, ponds, or lakes. The expert noted that snails with abnormal odors, a lack of reflexes when touched, or unusual buoyancy may be decomposing or harbor parasites such as liver flukes and intestinal worms.

Following this, a seafood vendor with 20 years of experience issued warnings regarding the selection of eels. He cautioned against purchasing dead or limp eels, noting that bacterial decomposition can produce toxins like histamine that remain stable even after cooking. To ensure freshness, consumers are advised to look for firm flesh that returns to its shape when pressed and to avoid any specimens emitting sour or pungent odors.
