NOROVIRUS Virus that is also called Norwalk Virus-the winter vomiting virus You can have this illness many times in your life and is the most common cause of acute gastroenteritis in the US Causes diarrhea, nausea, vomiting, stomach pain Spread direct contact with infected person, contaminated food and drinks, and on surfaces Source: produce, shellfish, ready-to-eat foods, or any food contaminated with vomit or feces from an infected person Wash hands after using the toilet; avoid food preparation with bare hands; clean & disinfect surfaces No specific treatment; resolves within a few days Can be serious for young children or the elderly PREVENTION: WASH YOUR HANDS thoroughly after using the bathroom or changing diapers and before preparing or eating food. WASH YOUR HANDS after contact with animals or their environments (at farms, petting zoos, fairs, even your own backyard). COOK meats thoroughly. Ground beef and meat that has been needletenderized should be cooked to a temperature of at least 160°F/70˚C. It’s best to use a thermometer, as color is not a very reliable indicator of “doneness.” AVOID raw milk, unpasteurized dairy products, and unpasteurized juices (like fresh apple cider). AVOID swallowing water when swimming or playing in lakes, ponds, streams, swimming pools, and backyard “kiddie” pools. PREVENT cross contamination in food preparation areas by thoroughly washing hands, counters, cutting boards, and utensils after they touch raw meat. If food is prepared more than two hours before serving, keep hot foods hot (over 140° F) and cold foods cold (40° F or under). Store cooked food in a wide, shallow container and refrigerate as soon as possible. Keep HOT food HOT and COLD for COLD
