Authorities in the United States are stepping up testing in the wake of the horse-meat contamination that has affected Europe in recent months.
The discovery of horse meat in ready-to-eat processed beef products in the European Union resulted in tens of millions of items being pulled from shop shelves.
The scandal has revealed the complexity of the food chain and its potential vulnerability to rogue traders.
A directive from the Food Safety Inspection Service, a division of the US Department of Agriculture, lays out the plans for increased inspections.
The directive increases “species testing” in a bid to detect any signs of fraudulent products.
Inspectors will boost testing of meat products from Iceland, Ireland, Poland and Britain, including Northern Ireland.
There will also be more testing of imported raw ground beef or veal, and ready-to-eat products.
It is understood that meat imports from countries involved in the horse-meat scandal are limited.
