NEW YORK – Coca-Cola Co. said Thursday it alerted the Food and Drug Administration after it discovered via testing its own and competitors’ products that some Brazilian growers had sprayed their orange trees with a fungicide that is not approved for use in the United States.

The FDA had said Monday that an unnamed juice company alerted it in December after detecting low levels of the fungicide in orange juice products after testing its own and competitors’ products.

Most orange juice products made by Coke and other companies contain a blend of juice from sources including Brazil.

Atlanta-based Coca-Cola did not say which of its own and others’ products it tested contained the fungicide. Its own orange juice products include Simply Orange and Minute Maid.

“This is an industry issue that affects every company that produces products in the U.S. using orange juice from Brazil,” Coca-Cola spokesman Dan Schafer said.

The FDA has said the low levels of the fungicide aren’t a safety risk but the agency will increase testing to make sure the contamination isn’t a problem.
