Thousands of parents have been left worried about what they may have fed their children after Cow & Gate and Tesco said they were recalling 15 varieties of baby food jars from stores in the UK amid concerns some may have been "tampered with".

Several police forces are investigating but so far no arrests have been made.

The Food Standards Agency (FSA) said 15 products are being withdrawn as a "precautionary measure" and anyone who bought them is being told not to feed them to children.

The recall involves 7+ month Cow & Gate jars of baby food brought from Tesco.

If you have brought any of the products listed below, they can be returned to the Tesco store from where they was bought for a full refund.

Here are all 15 products:

Many parents have been left angered by a lack of clarity over how the products may have been tampered with and what the results could be for their children if they have already eaten the products.

Trina Whyte fed her son Cruz some of the Cow & Gate food she brought from Tesco and wants answers about the risks, if any, that her son is facing.

"They haven't really taken into consideration how everyone is feeling, mums like myself who have given our child the product, because we don't know.

"There are loads of question marks.

"We don't know what we've given them.

"I don't know if in a couple of days he's going to be sick or anything and I don't know if it will be to do with that."

Cow & Gate's Facebook page has been inundated with messages from worried parents.

"I've literally fed my daughters these for two days... what way have they been tampered with?" one parent wrote.

A response from Cow & Gate read: "If you baby has already eaten one of our jars and you have any concerns they are unwell, then please speak to your healthcare professional."

Another customer said: "You really need to explain in what context these products have been tampered with."

The company replied: "Further details cannot be shared at this time."
