The foods that most often trigger allergic reactions are:

  1. Milk
  2. Eggs
  3. Fish
  4. Tree nuts (e.g., almonds, walnuts, pecans)
  5. Peanuts
  6. Wheat
  7. Soybeans

Clean Hands

Washing your hands the right way can stop the spread of illness-causing bacteria.

Here’s how to do it:



  • Wet your hands with warm water and apply soap.
  • Rub your hands together and scrub them well. Make sure to scrub the backs of your hands and between your fingers.
  • Rub your hands for at least 20 seconds. Sing the Happy Birthday song if you need a timer.
  • Rinse your hands well under running water.
  • With the water still running, dry your hands using a clean towel and use the towel to turn the faucet off.
