Listeria is a harmful bacteria that thrives in ready-to-eat foods that have already been cooked when purchased.
The products include snap frozen vegetable mixes, corn kernels, quick-steam carrot, broccoli and cauliflower mixes, and pea, carrot and sweet corn mixes.
The food chain reportedly said its food products are independently tested at random.
"The products affected contain a particularly risky strain of listeria and are being recalled as a precautionary measure to ensure consumers are protected, but particularly vulnerable populations", May said.
Listeria is found widely in the environment, but is particularly risky for pregnant women and their unborn babies, and can cause death in people with compromised immune systems.
