Canadians with upcoming trips to Mexico should take note of a recent update to the government’s travel advice for the country.
On Tuesday, the Government of Canada shared health information for travellers heading to Mexico, warning of the possible risk of cyclosporiasis.
“Cyclosporiasis is a common illness among travellers to this destination,” warns the update. “It is caused by a parasite called Cyclospora.”
According to the statement, the infection can be caused by eating food or drinking water that contains the parasite; however, it’s unlikely to spread between people.
Those infected experience the most common symptom, which is watery diarrhea. But if it’s not treated, these symptoms could last for a few days or even up to a few months, with some lasting six to seven weeks. There’s also a chance that symptoms can disappear only to return later on.

Preventing cyclosporiasis can be difficult because simply washing produce before consuming it doesn’t always get rid of the parasite that causes the illness. The Public Health Agency of Canada (PHAC) states that treatment is available. Prescription medicine can treat the illness, with symptoms improving within two to three days. But it could take weeks until intestinal issues disappear entirely.
To reduce the risk of infection, make sure to avoid eating food that’s been washed using local drinking water, and only drink water from a safe source. Make sure you only eat cooked food, and if you’re eating fruit, make sure that it’s something you can peel yourself.
The PHAC advises Canadians to cook produce that’s “imported from countries where Cyclospora is found.” It also emphasizes the importance of following safe food handling practices.
