Waitrose Recalls Essential Pitted Black Olives Over Listeria Contamination Fears
Waitrose has issued an urgent recall of its Essential Pitted Black Olives after the Food Standards Agency detected Listeria monocytogenes contamination, warning customers not to eat the product and to return it for a full refund.
Waitrose has issued an urgent recall of its Essential Pitted Black Olives after the Food Standards Agency identified contamination with Listeria monocytogenes, the bacterium that causes the serious foodborne illness listeriosis. The supermarket chain is instructing customers who purchased the affected product not to eat it and to return it to any Waitrose store for a full refund.
The recall notice, published by the Food Standards Agency, applies specifically to Waitrose Essential Pitted Black Olives. The contamination was discovered during routine testing, prompting the retailer to act swiftly in removing the product from shelves and alerting the public. The FSA has classified the recall as a health risk, urging consumers to check their cupboards and refrigerators for the affected item.
Listeria monocytogenes is a particularly dangerous pathogen for certain groups. While healthy adults may experience only mild flu-like symptoms, the infection can be severe or life-threatening for pregnant women, newborns, the elderly, and individuals with weakened immune systems. In pregnant women, listeriosis can lead to miscarriage, stillbirth, premature delivery, or serious infection in the newborn. The FSA routinely issues recalls when such contamination is detected to prevent potential outbreaks.
Customers who have bought the olives are being told not to consume them under any circumstances. Instead, they should return the product to their nearest Waitrose store, where they will receive a full refund without needing to produce a receipt in most cases. The retailer has also posted point-of-sale notices in its stores to alert shoppers who may not have seen the recall online.
The recall is the latest in a series of food safety incidents affecting UK supermarkets in recent years. Listeria contamination in ready-to-eat products such as olives, soft cheeses, and pre-packed sandwiches has prompted similar warnings from other retailers. The FSA works with businesses to ensure affected products are quickly withdrawn from sale and that the public is informed through its recall information service.
Waitrose has not disclosed how many packs are affected or which specific batch codes are involved, but the recall notice is expected to include details such as use-by dates and pack sizes. Shoppers who are unsure whether their purchase is part of the recall are advised to check the FSA website or contact Waitrose customer services for guidance.
The incident highlights the ongoing challenges facing the food industry in maintaining strict hygiene standards across supply chains. Olives are typically imported and processed in bulk before being packaged for retail, creating multiple points at which contamination can occur. Producers and retailers are required to conduct regular testing and maintain detailed traceability records to manage such risks.
For consumers, the advice is straightforward: do not eat the product, return it to a Waitrose store, and seek medical advice if symptoms of listeriosis develop after consuming the affected olives. Symptoms can include fever, muscle aches, nausea, and diarrhoea, and may take up to 70 days to appear after exposure.
Waitrose has apologised for any inconvenience caused and said it is working closely with the FSA and its suppliers to investigate the source of the contamination. The recall remains active while the investigation continues, and further updates may be issued if additional products are found to be affected.
