It causes a severe gastrointestinal illness with nearly half of cases ending up in hospital.

How can you reduce your chances of catching STEC?

The best prevention is regular hand washing especially before eating, after helping out on a farm, and after touching animals. 

Other ways to reduce your chances of catching STEC include cooking meat well, boiling untreated water and raw milk before drinking it, and not swimming in water where you can’t see your feet.
