• Foodborne illness peaks in the summertime.
  • Bacteria multiply more quickly in warmer temperatures.  Bacteria can double in as little as 20 minutes when food is in the ‘danger zone’ (between 40 and 140 degrees).
  • Never leave food out of a refrigerator or cooler for more than 2 hours.  If the temperature is above 90 degrees, food should not be left out for more than one hour.
  • When visiting an on-site food vendor, like those at festivals, check to make sure:
    • The work station is clean.
    • The vendor has a way for employees to wash their hands.
    • Employees wear gloves or use tongs when handling food.
  • Washing your hands is the most important thing you can do to stay safe and healthy.
  • Wash your hands with soap and water for at least 20 seconds.
    • Always wash hands after using the restroom, going on a ride, touching animals or playing in the water.
    • You should also wash your hands after removing dirty clothes or shoes.
    • Be sure to wash your hands before eating or drinking.
    • Have hand sanitizer or wipes in case there’s not a nearby place to wash your hands.
  • If you do get sick, it’s important to report it, even if you’ve already recovered.  
  • You can call the Mesa County Public Health reporting line at (970) 254-4120  or fill out this form on our website.
