The legal firm of Marler Clark states on their website that there are 1.4 million cases of salmonella poisoning each year and 95% of these are food related! 31% of all food related deaths are due to salmonella. They also state:
“Salmonella infection occurs when the bacteria are ingested, typically from food derived from infected food-animals, but it can also occur by ingesting the feces of an infected animal or person. Food sources include raw or undercooked eggs/egg products, raw milk or raw milk products, contaminated water, meat and meat products, and poultry. Raw fruits and vegetables contaminated during slicing have been implicated in several salmonella outbreaks.”
Vegans have little worry since they do not eat animal related products and can’t contaminate their vegetables from a cutting board used to cut meat. You do have to be careful when eating out.
