Fears over salmonella in guacamole and other dips have sparked a massive product recall affecting Tesco, Waitrose, Co-op and Sainsbury’s.

Nottinghamshire shoppers are being told to take the affected products back to the stores where they were bought – and they will be given a refund.

The Food Standards Agency said Bakkavor was recalling a number of its chilled guacamole products due to the possible presence of the bacteria.

A spokesman for the agency said: “The use-by dates for the products are up to and including July 2, 2016, and have been recalled as a precautionary measure because the products might contain salmonella. Symptoms caused by salmonella usually include fever, diarrhoea and abdominal cramps.

“The affected products have been supplied to the following UK retailers: Co-op; Tesco; Sainsbury’s; and Waitrose.

“Bakkavor is recalling the products from the retailers listed above. Product recall notices have been displayed in the retail stores that sell the products, explaining to customers the reason for recall and the actions they can take if they have bought the affected product.
