Inadequate knowledge of food borne diseases and their causes Improper food handling techniques Unsustainable environment

Various researches have been carried out on both food handlers and on food from local canteens and restaurants The study by Smith, Agomo, Bamidele, Opere and Aboaba (2010) showed the knowledge of food handlers about typhoid fever

Smith et al. (2010) showed that 27.7% of food handlers do not wash hands before preparing food 28.1% used only water to wash hands after using the toilet 90% had heard of and know about typhoid fever

However, 15.6% of these did not know how it was contacted Okolie, Omonigbehin, Badru, and Akande (2011) isolated pathogenic bacteria from food sold in private primary schools in Akoka, Lagos. Staphylococcus aureus, Bacillus cereus, Escherichia coli and Pseudomonas specie were all isolated from the food samples
