It takes several steps to get food from farm to fork. We call these steps, "The food production chain". Contamination can occur at any point along this chain during production, processing, distribution and preparation.
Small children/babies are incredibly prone to food poisoning, pregnant moms, the elderly and those that are immunocompromised, especially HIV infections and cancer patients.
The World Health Organisation (WHO) says that 1 in 10 people worldwide, fall sick from food poisoning. Within that 10%, 420 000 people worldwide incur severe infections or complications from food poisoning and die from food poisoning each year.
Food poisoning can be defined as an illness caused by consuming food or drink that has been contaminated causing nausea, vomiting or diarrhoea.
