Eleven schools in three different hygiene categories were given hygiene training as an intervention to
reported low hygiene standards. Staff hygiene knowledge scores, food temperature, food service time
and microbiological quality of jollof rice (cooked rice in tomato sauce and fish) were measured before
and after the intervention. Descriptive statistics and Wilcoxon's Signed- Rank Test for repeated measures
on SPSS were used to evaluate the effect of GHP intervention. Staff hygiene knowledge and practice
scores, food temperature, aerobic colony count (ACC) and Staphylococcus aureus load in ready to eat (RTE)
meal improved significantly (p 0.05). Food hygiene training remains an essential legal and industrial
requirement.
