The Public Health Agency of Canada is collaborating with provincial public health partners, the Canadian Food Inspection Agency, the Department of Fisheries and Oceans and Health Canada to investigate 67 Canadian cases of *Vibrio* parahaemolyticus infections in British Columbia and Alberta linked to raw shellfish. The majority of the illnesses have been linked to the eating of raw oysters.

In Canada, a total of 67 cases have been reported in British Columbia (48) and Alberta (19). One person has been hospitalized. No deaths have been reported. Individuals became sick between June 1 and Aug. 7, 2015, and all reported consumption of raw shellfish, primarily oysters. The investigation is ongoing to determine the source and distribution of these products. The risk to Canadians is low, and illnesses can be avoided if shellfish are cooked before being eaten. People with weakened immune systems, young children, pregnant women and older adults are at increased risk for developing complications if they get sick. Most people recover fully within a week. *Vibrio* is a naturally occurring bacterium that can be present at high levels in coastal waters during periods of increased water temperatures. Most people come in contact with *Vibrio* by eating raw or undercooked shellfish, especially oysters. Foods contaminated with *Vibrio* may look, smell and taste normal. The following safe food practices will reduce your risk of getting sick from *Vibrio* and other foodborne illnesses.

- Do not eat raw shellfish.
- Cook shellfish thoroughly before eating, especially oysters. Shellfish should be cooked to a safe internal temperature of 74 degrees C (165 degrees F).
- Discard any shellfish that do not open when cooked.
- Eat shellfish right away after cooking and refrigerate leftovers.
- Always keep raw and cooked shellfish separate.
- Avoid eating oysters, or other seafood, when taking antacids as reduced stomach acid may favor the survival and growth of *Vibrio* species.
- Always wash your hands for 20 seconds with soap after using the bathroom.
- Avoid exposing open wounds or broken skin to warm salt or brackish water, or to raw shellfish. Wear protective clothing (such as gloves) when handling raw shellfish.
- Wash your hands well with soap before handling any food. Be sure to wash your hands, cutting boards, counters, knives and other utensils after preparing raw foods.

People infected with *Vibrio* can experience a wide range of symptoms. Some do not get sick at all, while others feel as though they have a bad case of stomach flu. Few people get seriously ill. Most people develop one or more of the following symptoms 12 to 24 hours after being infected with the bacteria: watery or bloody diarrhea, stomach cramps, nausea, vomiting, fever, headache, or chills. Illness can last up to three days, and severe illness is rare. Patients should drink plenty of liquids to replace fluids lost through diarrhea.
