A Morrisons Busy Bee children's party cake has been withdrawn because it may contain a food bug.
The UK's fourth largest supermarket is withdrawing its £10 fresh cake because it may be contaminated with Salmonella.
The bacteria causes food poisoning that leads to diarrhoea, stomach cramps and sometimes vomiting and fever.
On average, it takes from 12 to 72 hours for the symptoms to develop after swallowing an infectious dose of salmonella and the effects can last up to seven days .
Young children and the elderly with weak immune systems are a greater risk of becoming severely ill.
The cakes which are a soft sponge filled with lemon curd and buttercream, wrapped in icing and hand decorated with icing flowers and bees, have a best before of August 4.
The Bradford-based supermarket said: "Routine testing has identified that a low level of Salmonella may be present in the above product.
"As a precautionary measure, we are asking all customers who have bought this product not to consume it and to return it to their nearest Morrisons store where they will receive a full refund.
"No other products or date codes are affected by this issue and we apologise for the
inconvenience this has caused."
The Food Standards Agency added: "If you have bought the above product, do not eat it. Instead take it back to the retailer where you will be given a full refund."
