Irish tourists jetting off to Spain have been warned to stay vigilant after a number of holidaymakers were diagnosed with infections of nasty parasites.

The HSE has issued advice on protecting yourself from a condition called cryptosporidiosis, also known as crypto after tourists returning from Spain, especially Salou in Catalonia, complained of having intestinal issues. Some of the main symptoms of the infection include 'watery diarrhoea,' but the illness can also cause dehydration, weight loss, stomach cramps, fever, and nausea, CorkBeo reports.

The HSE is warning people to practice good hygiene as the infection can spread through touch after handling food, especially raw meat, or live animals. People have also been warned to take care when drinking tap water.

They went on to advise people against using ice in drinks as ice cubes can often be contaminated with dangerous bacteria. Tourists have also been warned to avoid undercooked shellfish and dodgy street vendors.

Those who have had the illness have been asked not to go swimming in shared pools for at least a fortnight after the symptoms have cleared up, as the bug is resistant to chlorine.

In a healthy person, the symptoms caused by cryptosporidiosis should clear up in a week or two, but the infection can be much more serious for people with compromised immune systems.

And as part of the HSE's official advice, beer and wine are deemed 'generally safe' for consumption as well as bottled mineral water and hot drinks.

It's the latest warning to those travelling out of Ireland and onto the continent, with another warning for Irish holidaymakers urged to avoid bringing bedbugs home from their travels as France deals with a scourge of the creepy crawlies - which now look to be becoming resistant to pesticides.
