Studies in Egypt and elsewhere have found street foods to compare not【C12】______with hotel foods in respect of contamination with micro-organisms — some street foods were found to be contaminated with pathogens,【C13】______so were foods from four-and five-star hotels in the same area.
Hazardous chemicals have been found in street foods, and food exposed for sale on roadsides may become contaminated by lead from vehicle【C14】______.

Similarly foods which are【C20】______cooked and eaten at once are safer than precooked food kept at high temperatures for several hours.
