A salmonella outbreak that has left 12 people in hospital has been linked to a factory in Bolton.
The Food Standards Agency (FSA) is advising people to avoid several pork scratching products purchased since February.
Tayto Group Ltd is withdrawing some Mr Porky, Jay’s and The Real Pork Crackling Company products.
It comes after testing found 176 reported cases of salmonella poisoning across the UK over the last year could be linked to them.
The products are manufactured at Tayto Group's factory in Westhoughton, the FSA has said.
Production was voluntary halted at the site after a possible link was identified earlier this month.
Shoppers are advised not to eat any of the products involved in the recall and instead, return them to the store where they were bought for a full refund.
Tina Potter, Head of Incidents at the Food Standards Agency, said: "We are advising consumers not to eat any of the products listed in the FSA alert. It is really important that consumers follow this advice to avoid the risk of becoming ill with salmonella poisoning.
"The food business involved has voluntarily suspended its production to put additional controls in place to improve the safety of their products and they have decided on a voluntary basis to withdraw and recall all of the products within shelf-life produced at this site.”
Symptoms of salmonellosis typically resolve themselves and include diarrhoea, stomach cramps, nausea, vomiting and fever.
However, symptoms can be more severe and lead to hospitalisation, especially in the very young and those with weakened immune systems.
Dr Lesley Larkin, Surveillance Lead, Gastrointestinal Pathogens Unit at Public Health England, said: “We have established a link between the 176 cases based on the analysis of data obtained through whole genome sequencing and epidemiological investigations.
“These investigations, together with those carried out by local authorities, have indicated the source of infection is pork scratchings produced by a single company in the UK.
"The Food Standards Agency has acted on these findings to mitigate any further risk to public health from the contaminated food.
“Salmonella can be spread from person to person, so anyone affected should adhere to good hygiene practices including washing your hands thoroughly after using the bathroom and avoiding handling food for others if you have symptoms.
"Anybody with concerns that they have symptoms of salmonellosis should contact their GP or call NHS 111.”
Tayto Group Ltd operates from six sites across the UK and manufacturers a range of products, including pork scratchings, crisps and popcorn.
A spokesman for the business told the BBC: "The safety of our products is of the utmost importance, which is why we have taken the decision to initiate a precautionary recall for some products.
"We are working closely with the local environmental health team and the FSA at this time."
