With thousands handling the handle of the machine every day to dispense the ice-cream, it’s a hotspot for harmful germs. And given that most people dispense the ice-cream with their favoured hand and then eat the soft serve afterwards with that same hand, the bacteria will likely end up in your mouth.
To avoid it, experts suggest wrapping a napkin around your ice-cream - or around the handle while you’re dispensing the soft serve.
Another dangerous food is the communal condiments. Again, with so many people touching the various sauces and condiments, the potential to pick up lots of nasty bacteria is high.
To guard against it, experts suggest requesting sachets of condiments or using anti-bacterial wipes before and after using communal items.
The other high-risk food onboard is - not surprisingly - raw fish sushi. Although cruise ships take a lot of care to ensure the fish has been stored at a high standard, some health experts say it’s best to give sushi at the all-you-can-eat buffet a miss.
While eating plates of non-stop sushi is a dream come true for fans of the Japanese cuisine, experts say that it’s hard to know how long the morsels have been sitting there. And even when they're chilled at the buffet, ensuring they're all kept at a bacteria-blocking temperature can be tricky.
But with literally thousands of other food options, it’s not like you don’t have lots of choice right?
