Tim Johnson (D-SD) introduced another measure requiring labels on imported meat and meat products to list the country of origin. Labeling bills are strongly supported by domestic growers and other producers who would face less competition though they are portraying the legislation as a food safety issue. Retailers processors and manufacturers of meat products however say country of origin labeling will add more costs without improving food safety. Meanwhile the American Frozen Food Institute (AFFI) is urging Congress to press the U.S. Customs Service to withdraw its proposed rule to mandate front-panel country of origin marking for frozen produce with imported content. AFFI says the requirement would harm the international trade of frozen produce and set the stage for further regulation of other classes of imported goods.
