A fan-favorite freezer staple sold at Walmart and Aldi has been pulled from shelves over fears it could be contaminated with salmonella.

Shoppers are being urged to check their freezers after health officials widened an alert covering several meat and poultry products made with recalled dry milk powder.

The warning now includes frozen chicken bacon ranch pizzas sold under Walmart’s Great Value label and breakfast pizzas sold under Aldi’s Mama Cozzi’s brand.

Great Value pizzas sold at Walmart included in the recall are the thin crust chicken bacon ranch and the stuffed crust chicken bacon ranch. 

The thin crust chicken bacon ranch and stuffed crust chicken bacon ranch with best buy dates between February 11 and March 8 as well as stuffed crust chicken bacon ranch with a best buy date of April 13 were affected. 

The recalled breakfast pizzas sold at Aldi under its Mama Cozzi’s label include: the biscuits crust sausage and cheese breakfast pizza, in addition to the breakfast pizza with cooked pork belly crumbles, cooked bacon topping, pepper and onion.

Officials say the concern stems from dry milk powder used in the products, which may have been contaminated with salmonella. 

Walmart spokesperson said that the health and safety of its customers is 'always a top priority.' 

'We have issued a sales restriction and removed this product from our impacted stores,' the spokesperson added. 'We are working with the supplier to investigate.'

Health officials warned customers not to eat the affected products, even if they have been cooked thoroughly, due to the potential salmonella risk.

Shoppers are told to check their freezers and throw away any impacted items or return them to the store for a refund. 

So far, no illnesses have been officially linked to the recalled pizzas.

This health warning is just the latest in a growing list of products linked to contaminated dry milk powder - putting even more fan-favorite foods at risk of salmonella. 

Salmonella bacteria invade and destroy the cells that line the intestines. 

This makes it hard for the body to absorb water, which can result in stomach cramps. 

The water leaves the body in the form of diarrhea. 

In life-threatening yet rare cases, Salmonella can lead to infections in the brain, bones, joints, heart lining or urinary system. This could lead to severe complications like meningitis, osteomyelitis, endocarditis or even sepsis.

Severe complications are most dangerous for vulnerable people, including young children, the elderly, and those with weakened immune systems.

In these cases, patients require intravenous antibiotics, fluids and close medical monitoring to fight the systemic infection and prevent life-threatening organ failure.
