Public health authorities are investigating 47 illnesses from scombrotoxin fish poisoning linked to yellowfin tuna that may have been sold fresh or frozen.

The FDA recommends throwing out the tuna, also called ahi tuna, imported from Truong Phu Xanh Co. of Vietnam. The investigation with state health officials identified the company as the common supplier of tuna likely eaten by most of the ill people. The fish might have come as ground tuna meat, poke cubes, steaks or loins, and some products may not have expired yet.
