The U.S. Food and Drug Administration (FDA) says its inspectors are continuing their investigation at the Sunland Inc. production facility in Portales, NM.

That facility, with the capacity to produce six tons of peanut butter per hour, is associated with the current multistate outbreak of Salmonella Bredeney.

Sunland expanded its recall to include about 100 brands, including peanut butter and other products made with nuts and seeds. Sunland announced and expanded its recall on Sept. 24 after meetings with personnel from both FDA and the federal Centers for Disease Control and Prevention (CDC).

A complete Sunland recall list is available here, including the brand it makes for Trader Joe’s that was originally recalled Sept. 22.

The rare serotype of Salmonella has been found in 30 people across 19 states. Salmonella Bredeney is a serious threat to children, the elderly and those with serious infections. Four of the confirmed cases are known to have required hospitalization. No deaths have been reported.
