A retail labeling law for fresh meats, fruits and vegetables will be implemented over the next six months on an interim basis to give all parties time to adjust and comply with the regulations.

Federal officials said Tuesday that consumers will be able to tell where those products come from by looking at labels, stickers, placards and stamps placed on them in grocery stores.

Farm groups have long pushed for country-of-origin labels.

Meat from animals that are born, raised and slaughtered in the United States must be designated as such.

Another label will spell out multiple countries of origin, such as “Product of U.S., Mexico and Canada.”
