Health experts have issued a warning over trendy ‘raw’ cheeses after a man died from listeria poisoning, as the popularity of unpasteurised dairy surges in the UK.

Whether it’s Brie de Meaux, Comté or classic Parmigiano Reggiano, many of the world’s best-known cheeses are made using raw milk, which has not been heat-treated to kill bacteria.

Supporters say this preserves flavour and beneficial microbes - but scientists warn it can also allow dangerous pathogens to survive.

West Sussex painter Roger Parkes fell seriously ill and died in February 2023, days after eating a ‘Valentine box’ of artisan cheeses bought by his wife, Carina.

Following his death, Wiltshire-based producer The Old Cheese Room recalled batches of its Baronet Reblochon. An inquest later concluded Mr Parkes died from multiple organ failure and meningitis linked to listeria infection.
