As she made a chilli con carne for her three kids, a mum was horrified to find what looked like a BRAIN in a packet of sieved tomatoes she'd bought from discount store Lidl.
Julleen Marter, 47, said she spotted chunks of grey, spongy matter floating in the sauce when she poured the passata into a pan.
When she looked inside the packet she discovered a strange 'brain-like' object, measuring 10cm in diameter.
And to add insult to injury, Julleen, from Worcester, claims a Lidl's customer service worker laughed at her when she rang up to complain.
Julleen said: "After pouring the tomato passata in, I noticed the consistency was not as it should be.
"I also noticed the normally bright red sauce was turning a really horrible black colour.
"I realised that there was something in the bottom of the carton so proceeded to cut it open with scissors and to my horror discovered something which I can only describe as strange.
"I am not sure if it was animal or plant but it looks like a brain-type material.
"It's like something out of a horror movie. I was so disgusted I almost threw up.
"At the moment it is frozen because that is what environmental health told me to do.
"I'm waiting for them to come back to me to take it away and have it tested. "I rang Lidl and the advisor just giggled and said it was probably just a tomato.
"I have examined the object and it certainly isn't a tomato. It's spongy and looks like a small brain.
"She asked me to send them an email and a photograph of the object which I did but I have not heard back at all.
"I don't think I will be going back there again. I think I shall be staying away for a while.
"I just need to put my mind at rest as I am concerned a whole batch may have been contaminated. "I don't want compensation, I just feel that this has now become a public health issue."
Lidl told Metro the company was investigating the incident with its supplier.
A spokesman said: "We take any situation of foreign bodies very seriously. We do apologise if that was how it came across."
A spokesman for Worcestershire Regulatory Services - the umbrella body for Environmental Health and Trading Standards - said people should report any similar issues to them.
"We would also advise people to keep as much information as possible including the item itself, the packaging and any receipts - it will all help," he said.
