A recall of Kinder Surprise eggs has been extended to more Ferrero products, including Kinder Mini Eggs and Kinder Egg Hunt Kits because they might be contaminated with Salmonella, the Food Standards Agency has said.

In a statement on Wednesday, the European Centre for Disease Prevention and Control said chocolate products were identified “as the likely route of infection,” adding that children mainly under 10 years of age were affected. Chocolate firm Ferrero had been recalling some batches of eggs as a precautionary measure while investigations continued into the link. European health officials say they are investigating a “rapidly evolving” outbreak of salmonella in 134 children that appears to be linked to chocolate Easter eggs that normally contain a surprise toy inside. An initial outbreak saw 63 people in the UK, mostly children under the age of five, become infected with salmonella linked to Kinder Surprise eggs. However, it has since been announced that more products from the firm's Kinder line, including Mini Eggs and Kinder Egg Hunt Kits are also being recalled amid fears of further contamination.

This is in connection with a potential link to a salmonella outbreak. A number of these cases have been young children," the FSA said.
