Advice for Travellers
Following safe food and water precautions during travel reduces your risk of infection. In particular:
- drink only boiled or bottled water
- be aware that cyclospora is not killed by most water purification tablets, portable filtration systems or disinfectants (including standard water chlorination)
- avoid eating unpeeled raw fruit and vegetables, especially berries, herbs and salad leaves
- be aware that washing food in drinking water is unlikely to remove all of the germs from fruit and vegetables
