Supermarket chain Jumbo is recalling 135 different types of pre-packed cold meat ranging from salami to ham because of a listeria scare.

Listeria may have been found in one of three factories used by the Offerman meat company to produce chicken and pork products for Jumbo, prompting the recall. Four Aldi products made by the same factory are also being recalled and other supermarkets may follow.

Shoppers are being urged to return the products to their local stores and their money will be refunded. Cold cuts currently on the shelves are safe to eat, the supermarket chain said.

Listeria is a bacteria which primarily affects the elderly, pregnant women, new-borns and people with weak immune systems. It is particularly dangerous to pregnant women and can cause miscarriages.

The bacteria is usually found in food which is eaten cold, such as pre-prepared meats.
