Food Poisoning is a growing public health problem causes considerable socio-economic impact on cost and work load of health care systems, loss of productivity and harming tourism and trade. The burden of foodborne diseases to public health and welfare and to economies has often been underestimated due to underreporting and difficulty to establish causal relationships between food contamination and resulting illness or death. It is estimated that, every year 220 million children contract diarrhoeal diseases and 96 000 die. Unsafe food creates a vicious cycle of diarrhoea and malnutrition, threatening the nutritional status of the most vulnerable.

According to Food and Agriculture Organisation (FAO) estimated that one in 10 people in the world (about 600 million), may sick after eating contaminated food and about 420,000 die every year, as result of this, loss of 33 million healthy life year.  Unsafe food poses global health threats, serious public health issue causing many deaths and losing productive days.
