Fighting Norovirus with Cranberries

Maine cranberries

Cranberries have beneficial properties for our health, including kidney and urinary tract health.  New research has found another use for cranberries, to fight the foodborne illness Norovirus associated with fresh produce.

This preliminary study is a new treatment using cranberry juice and fruit extract to make an edible coating that is sprayed onto produce. When used along with a low dosage of gamma irradiation, or cold pasteurization, the study showed the coating eliminated contamination. Without the coating, the dosage of irradiation needed to kill norovirus is three kilograys. But with the cranberry coating, that dosage can be cut in half. This reduction can help preserve the quality properties of produce.

Norovirus is caused by person-to-person contact, touching contaminated surfaces, and consuming contaminated food or water.

Preventing Norovirus at Camp

Summer is coming! And many youth are gearing up to go on a camping adventure. Getting sick with norovirus at camp will ruin the fun quickly. Norovirus is contagious and will spread quickly when many people are in one location.

How can norovirus happen? An infected person can spread it with:

  • A simple handshake
  • Shared food or utensils
  • Contaminated food or water
  • Unwashed hands that touch contaminated surfaces.

Food Safety Education Month


The theme for the 2016 National Food Safety Education Month (NFSEM) is “Notorious Virus!” and is sponsored by the National Restaurant Association and ServSafe®.

Activities, videos, and other educational tools are available to help educate food service personnel about Norovirus and Hepatitis A. While targeted to food service, these materials can apply to anyone to help teach safe food handling.

Norovirus is the most common cause of acute gastroenteritis. It spreads easily and is often called the stomach flu. It transmits easily as it survives on surfaces that have been contaminated or from an infected person.

Handwashing is the best defense against Norovirus. Clean and disinfect areas contaminated by vomiting or diarrhea. If sick, do not handle food.
