A California nut grower and processor issued a nationwide recall of pistachios on Tuesday due to possible salmonella contamination, and authorities said consumers should avoid all pistachio products until more information was available.
The U.S. Food and Drug Administration (FDA) said several illnesses had been reported that may be associated with the contaminated pistachios. The FDA said it and the California Department of Public Health were investigating the matter.
The FDA said it first learned of the problem on March 24, when Kraft Foods Inc informed the agency that Back To Nature trail mix was contaminated. Kraft had identified the source of the contamination as Setton.
