Shrimp is the number one seafood choice in the nation. Most of it is farm-raised in other countries and imported to the United States. But some can come from China, India, Malaysia, Peru, Thailand, and Vietnam, reported WBAL-TV in Baltimore.

"They use antibiotics that are banned in the United States for use in shrimp farms, but still use them to ward off viruses," said Andrianna Natsoulas of Public Citizen. One of those banned antibiotics is chloramphenicol — widely used in third-world countries because it’s so inexpensive.

The FDA said there’s also a potential side effect that comes with chloramphenicol — a rare blood disease called aplastic anemia that causes damage to bone marrow, rendering the body incapable of producing red blood cells.

In addition, "If you happen to get a salmonella strain, which also happens to be carrying a resistance gene, then your doctor may not be able to use certain antibiotics in terms of treating you," said Dr. Glen Morris, a specialist in infectious diseases at the University of Maryland School of Medicine.
