Maple Lodge Farms, Canada's largest independent chicken processor is introducing "a new high-pressure method of killing listeria and other bacteria in sliced luncheon meats after the package is sealed." Last summer 21 people died in the country after a listeria outbreak. The new technology "applies water under extremely high temperatures to the packaged product, has no adverse impact on the product itself," and "extends shelf life." Packages that have undergone the new process will display a "SafeSure" sticker. Other Canadian companies are using the process, which has government approval.
