               VIRUSES
               Viruses are protein wrapped genetic material, the smallest and simplest lifeform known, they
               are not complete cells and do not reproduce in food, but some viruses can survive cooking and

               freezing, and they can be transmitted to a human host by food or food contact surfaces.
               Humans are the most common source of virus and impeccable personal hygiene and safe food
               handling practices are required to minimise the risk of spreading a virus.
