In 2012, six BC residents became ill with
Hepatitis A virus after consuming a mixed frozen fruit blend; pomegranate seeds from Egypt were identified as the probably source. In 2011, a large outbreak that started in Germany caused nearly 4,000 illnesses through-out Europe. People became ill after eating raw sprouts in salads and sandwiches (fenugreek sprouts). The pathogen was a novel toxin producing
E. coli. Other high profile outbreaks related to fresh vegetables in recent years include spinach contaminated with E.coli O157:H7 in 2006, and jalapeno peppers contaminated with Salmonella in 2008. A BC spinach outbreak in 2001 led to the creation of guidelines for growers about the importance of managing water and fertilizer sources.
As a consumer there are actions you can take with your fresh fruits and vegetables (guideline), like washing your produce that will limit your exposure to harmful bacteria and other microbes.
Cooking all foods to an internal temperature of 74°C will also destroy most harmful bacteria.
