Manufacturers using food labels with the wording “may contain” have come under fire from the Food Standards Agency.

The FSA said that the meaning of “may contain” - often used by manufacturers to give the public information about possible nut contamination - is not as clear as it could be.

According to new research by the FSA people with nut allergies found “may contain” labels on pre-packed food inconsistent and confusing.

As a result a large proportion of the adults surveyed admitted to taking risks by eating some foods that had the warnings.

The FSA said it will work with industry and stakeholders to look at what improvements can be made.
