Varieties such as Mr Whippy can harbour bacteria and also increase the risk of listeria, if machinery isn’t properly cleaned or the ice-cream not pasteurised.

“It’s often something people don’t think about when they go on holiday”, says Annemarie. “As Mr Whippy ice-cream is softer, it’s more likely to have been kept at a higher temperature.

“Melted ice cream poses the same risk.”

Avoid the risk: “We can think about it in the same way as we might think about bottled water when going abroad – just be conscious, especially with the more at-risk groups of people I mentioned.” Or stick to hard, frozen ice-cream.
