The U.S. Food and Drug Administration has issued two recalls affecting Richmond County in recent weeks, according to Environmental Health Supervisor Mike Norton.

Norton noted the biggest concern in this area are nine ounce bags of Kraft Back to Nature Trail Mix. Anyone with this product should immediately log on to the FDA’s website and verify whether it is contaminated by checking against the UPC code and “best if sold by dates. “

The pistachio products in question were sold by Setton Pistachio of Terra Bella Inc., California, and may be infected with multiple strains of Salmonella, according to a release from the agency.

The recall affects approximately one million pounds of products.

“As always, we continue to monitor recalls issued by the FDA, and ensure that these products are removed from service,” Norton said in a county release. “We also want to make sure citizens are aware of these recalls as well.”

In the release he noted local environmental health specialists will be on the lookout for these products as they continue to inspect local eating establishments.

The following brands were sold in the state of North Carolina and are included in the recall: Whole Foods Market, Kar Nut Products, Kroger, Kraft Foods and Frito-Lay.

The FDA provides a searchable database of recalled products, which can be found at www.fda.gov/pistachios.

“Vendors are asked to voluntarily return these items,” Norton said.

He noted the county has not been forced to embargo these products, as it was during the recent recall of peanut products sold by the Peanut Corporation of America.

The county’s release urges citizens to avoid eating pistachios because the investigation is ongoing, and more products may be identified.

Salmonella can cause serious and sometimes fatal infections in young children, frail or elderly people and others with weakened immune systems, according to the FDA.

The second recall affecting Richmond County involves oysters harvested between February 24 and March 17 in the Gulf of Mexico off the coast of Mississippi, according to the FDA.

The agency is urging consumers to contact the place of purchase for oysters if they are uncertain of their origins.

These oysters may contain a food-borne pathogen called norovirus, whose symptoms include nausea, vomiting, diarrhea and some stomach cramping.
