TORONTO - The Canadian Food Inspection Agency is implementing new changes in Listeria testing and reporting requirements in plants producing ready-to-eat meat.

The agency says the enhanced measures will centre around early detection, reporting and control of Listeria risks by both the federal government and the industry.

Plant operators that produce ready-to-eat meat, such as cold cuts, will have to conduct more rigorous Listeria testing and immediately report any positive findings to the CFIA.

As of April 1, plant operators must have programs in place for testing surfaces that come in contact with food.

The agency also plans an expanded detection program for Listeria and other food-borne pathogens.

Maple Leaf Foods agreed to pay up to $27 million to settle class-action lawsuits after a deadly outbreak of listeriosis was traced to equipment at a processing plant.
