US regulators have told Campbell Soup that its Prego pasta sauce contains less vitamin C than advertised and have ordered the company to correct the problem promptly, according to a letter made public on Tuesday.
The label for Prego Three Cheese Pasta Sauce said the product contained 25 per cent of the recommended daily intake of vitamin C. Laboratory tests by the Food and Drug Administration showed the samples had 5.47 per cent or 8.33 per cent of the daily allowance, the agency said in a warning letter.
Campbell Soup spokeswoman Elizabeth Bingham Douglass said the product's label was incorrect. The company has told the FDA it will fix the problem by the end of May.
The FDA's letter was dated 12 March and posted on the agency's website on Tuesday. The FDA sends dozens of warning letters per year. The letters can lead to product seizures or injunctions, but most issues raised are resolved without further regulatory action.
