Gawler-based Wintulichs has recalled its 300 gram, 375g, 500g and 700g garlic mettwurst varieties, its 700g plain mettwurst and its 375g pepperoni mettwurst.

Wintulichs identified those products with a use-by date of April 8, 2020, did not meet the pH and water activity criteria required.

The products were sold at Woolworths, IGA and independent stores in South Australia.

Food Standards Australia New Zealand said consumers should not eat the recalled mettwurst and instead return them to where they bought them for a full refund.

SA Health said customer complaints to Wintulichs about "blown packaging" had led to testing identifying a "process failure" for the recalled batch.

"SA Health has no report of illness associated with consumption of these products at this stage," the department said in a fact sheet.

"If you are feeling unwell, please seek medical attention and inform your doctor that you have eaten the product and would like a faecal sample taken."

History of problems with mettwurst

In November, a possible listeria contamination led to the statewide recall of Barossa food manufacturer Kalleske Meats' plain mettwurst.

It issued the recall after testing on another product — which has been put on hold — turned up traces of listeria.

A similar recall happened in 2016 when South Australian company Linke's Central Meats issued a nationwide recall for its mettwurst and pepperoni.

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 continued to suffer severe health problems, including some who have had organ transplants.

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