Explosive Diarrhea Warning for UK Travelers to Mexico
30 Jul
Summary
- UK faces a surge in cyclosporiasis cases, primarily among Mexico travelers.
- The parasite contaminates food like salads, herbs, and fruits.
- Travelers advised to practice good hygiene and avoid raw produce.
The UK is experiencing a significant increase in cyclosporiasis cases, a parasitic infection leading to severe diarrhea. As of July 15, 2026, 67 cases have been reported in the UK, with a substantial number of affected individuals having recently traveled to Mexico.
Investigations reveal that many of these travelers stayed in resorts in Riviera Maya and Cancún, consuming various foods and drinks as part of all-inclusive packages. The parasite, Cyclospora, can contaminate fresh produce like salads, herbs, and soft fruits. While not naturally occurring in the UK, the risk to the general population is low as it doesn't spread person-to-person.
Public health advice emphasizes strict food and water hygiene for those traveling to affected regions. Recommendations include drinking bottled water, ensuring food is thoroughly cooked, and avoiding certain raw items such as unpeeled fruits, berries, and salad ingredients to mitigate infection risk.
