Potentially thousands of Asda, Tesco, Waitrose, Co-operative and Sainsbury’s own-branded chilled yoghurt products, supplied by Yeo Valley, are affected.
Lidl Ireland also recalled Coolree Creamery brand Irish Yogurt Selection with seeds from Northern Ireland stores.
The Food Safety Authority of Ireland (FSAI) said yoghurts sold in Lidl Ireland, Tesco Ireland and SuperValu are also affected - a list of products and date codes can be found here.
Asda was most affected recalling seven types of yoghurt, Co-op, Waitrose and Tesco three and Sainsbury’s two as well as The Collective Dairy brand withdrawn from some stores.
Yeo Valley said the rubber was found in a fruit conserve from one of its suppliers and it will be destroying yoghurts not yet sent to market.
It is unclear if it will continue supplying yoghurt to the supermarkets affected or working with the fruit conserve supplier.
The firm would also not tell us where and when yoghurts were produced or how the rubber got into products and was not spotted before being sent for sale.
Rubber found in fruit conserve
In a statement, Yeo Valley said the issue does not affect any of its branded products.
"Yeo Valley can confirm that a piece of rubber was found in a fruit conserve supplied by one of our suppliers. The supplier has identified the cause and has identified all fruit conserves, an ingredient used in fruit yoghurts, that may be affected.
“Whilst the risk is considered to be low, as a precaution, we will be disposing of any potentially affected yoghurts that have not yet been dispatched, as well as recalling the relevant batches of products from those affected retailers.
“We are working with the Food Standards Agency and the supplier in question to ensure it does not happen again. We would like to apologise unreservedly to all customers."
If consumers have bought any of the products they are advised not eat them and return them to their nearest store where they will receive a refund. A list of affected products can be found here.
