Unformatted text preview: Foodborne disease (food poisoning) tends to be regarded as a comedy illness—not pleasantPlay o to have, or talk about, but little more than an inconvenience. So easy to ignores the size of the illness burden.

Primary prevention of foodborne zoonoses is mainly a veterinary responsibility.
