Several porridge products in the UK have been recalled over a possible mice contamination at their manufacturing site.

The British porridge and oat drink brand Moma issued a warning for seven versions of its pots and two of its sachets.

Customers have been told not to eat the affected products and to return them to the place of purchase for a full refund.

The Food Standards Agency said in a statement on its website on Sunday: “Moma Foods is recalling various porridge pots and sachet products because of possible mouse contamination at the manufacturing site.”

It added: “These products may contain mouse contamination making them unsafe to eat.”

Point of sale notices will be displayed in all retail stores that sell the products and on stores’ websites. There is also an alert on Moma’s website.

The recall applies to the following porridge pots: almond butter and salted caramel; apple, cinnamon and brown sugar; banana and peanut butter protein; blueberry and vanilla; cranberry and raisin; golden syrup; and plain no-added sugar.

Moma has also asked customers to return almond butter and salted caramel porridge sachets, and the apple, cinnamon and brown sugar sachets.

None of its other products are affected, the company said.

Moma said: “Even though the chance of contamination of any of the above products being affected is low, we have taken this precautionary step to ensure the safety of our consumers.

“Any consumers who have purchased affected Moma porridge products are asked not to consume them. Instead, they should return the products to the store where they were purchased and a full refund will be issued.”

Moma Foods was started in a railway arch in Deptford, south-east London, in 2006 selling porridge and smoothies.
