Cow & Gate are urgently recalling 15 varieties of baby food sold in Tesco amid fears they have been "tampered with".
Shoppers who have purchased jars of the food for babies aged above seven months are urged not to use it and return it to the supermarket.
The company said the recall is a "precautionary measure" following "concerns that some jars may have been tampered with".
No other Cow & Gate supplements sold in Tesco or 7+ months jars sold in other stores are a safety risk, they said.
"We regret that this incident has happened and we are sorry for the concern and the inconvenience that this recall may cause," Tesco and Cow & Gate said in a statement.
The Food Standards Association added: "If you have bought any of the listed products, do not feed them to your baby.
"Instead, return it to the Tesco store from where it was bought for a full refund."
Anyone concerned can contact Tesco Customer Services on 0800 917 6897 or call Cow & Gate on 0800 977 8880. The full list of jars being recalled is available here.
