Inadequate knowledge of food borne
diseases and their causes
Improper food handling techniques
Unsustainable environment
![Page 12: Muinah Fowora Walden University 22 nd July, 2012](https://reader035.vdocuments.us/reader035/viewer/2022062511/55143629550346e7488b61ce/html5/thumbnails/12.jpg)
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
![Page 13: Muinah Fowora Walden University 22 nd July, 2012](https://reader035.vdocuments.us/reader035/viewer/2022062511/55143629550346e7488b61ce/html5/thumbnails/13.jpg)
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
![Page 14: Muinah Fowora Walden University 22 nd July, 2012](https://reader035.vdocuments.us/reader035/viewer/2022062511/55143629550346e7488b61ce/html5/thumbnails/14.jpg)
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
![Page 15: Muinah Fowora Walden University 22 nd July, 2012](https://reader035.vdocuments.us/reader035/viewer/2022062511/55143629550346e7488b61ce/html5/thumbnails/15.jpg)
Are there any existing interventions or
regulations to combat these problems?
