Food: New rules for labeling fresh produce and meat by country of origin went into effect in the US on September 30. Manufactures have six months to comply with the rules. However, loopholes in the law exempt processed foods and mixed vegetables. In addition, labels on meat cuts can show more than one country of origin. The legislation, which was passed by Congress six years ago, is expected to cost food producers $2.5 billion in its first year, according to estimates by the Department of Agriculture. But some foods are already labeled. According to the United Fresh Produce Association, 50% of fruits and vegetable are voluntarily labeled. Country of origin labeling for fish and shellfish have been required since 2005.
