Conclusions

There is a potential for floating vendors-to-food

contamination due to insufficient hygiene practices.

Most floating food vendors have knowledge of some

aspects of food safety and practices, several gaps

remain, posing a serious health hazard to consumers.

21

Conclusions The main problems were the infrequency of hand

washing, the storage of cooked food uncovered and

the accumulation of waste near the point-of-sale.

It is important that vendors should be supported

additional hygiene training,

and the routine inspection

code of practice22
