A possible listeria contamination has led to the statewide recall of a South Australian company's plain mettwurst.

Barossa food manufacturer Kalleske Meats issued the recall after testing on another product — which has been put on hold — turned up traces of listeria.

Listeria can cause flu-like symptoms and can take up to six weeks to appear.

The recall applies to the 500 gram mettwurst and bonus 150g product with a best-before date of May 11, 2020.

The processed meat product is sold in plastic shrink-wrap at Coles supermarkets in Port Lincoln, Burnside, Port Augusta, Gawler, Salisbury and Paralowie.

Food Standards Australia said listeria could cause illness in pregnant women, elderly people and those with weakened immune systems.

A similar recall happened in 2013, when South Australian company Linke's Central Meats issued a nationwide recall for its mettwurst and pepperoni.

At the time SA Health said the products were recalled because the safety of the manufacturing process could not be verified.

Earlier this month, South Australian cheesemaker Udder Delights voluntarily recalled 11 types of its cheese which were found to exceed the allowable limits of E. coli, which can cause diarrhoea, nausea and abdominal cramps.

In 1995 a number of people became sick and four-year-old Nikki Robinson died in Adelaide after eating Garibaldi smallgoods contaminated with E. coli bacteria.

The surviving victims were children and many continue to suffer severe health problems, including some who have had organ transplants.

It was one of South Australia's longest-running legal cases.
