Aldi has removed 38,000 bags of frozen vegetables from its shelves after a customer found half a rat inside one.
The supermarket giant has issued a recall for the bag of mixed greens and launched an urgent investigation after a grandmother found bits of rodent in the product whilst feeding her two-year-old granddaughter, The Mirror reports.
Pat Bateman, 60, said the discovery left her feeling "physically sick".
She told The Sun: "We had eaten almost all of the bag before we saw it - and what’s even worse - I fed it to my youngest granddaughter.
"It’s a wonder none of us ended up physically ill."
She took the evidence back to her branch of Aldi near Liskeard, Cornwall, where a manager apologised and offered her £30 off her next shop.
However Mrs Bateman didn't feel the company were taking it seriously enough so she sent pictures to Aldi's head office.
She has since been offered £500 compensation but still doesn't feel this is "enough".
According to the Sun, an internal Aldi report found there have been three complaints about "pieces of small rodent" in the the same product.
The mixed veg bag was removed from sale on January 5 as a result and an investigation launched.
Aldi said in a statement: "Following Mrs Bateman’s complaint, we removed this product from sale to prevent any further issues.
"We have suspended all orders from this production site whilst we investigate this matter."
