From the government advertisements and common media it is common belief that street foods are much less safe than restaurant foods. Yet when reading about street foods in Wikipedia I came across this claim that incidence of street food contamination is lower(or at least same) as restaurants.
Also from common sense it seems that the statistics should vary depending upon country, food etc.
Is there any more studies supporting (or not) this claim?
In face, research demonstrates that, despite theoretical risk, the incidence of street food is low - not higher than in restaurant foods

[Update] I am from India but it is hard to find any paper published for this in India. So the answer concerning any country where street food is common, is acceptable.
For raw or cooked food I am wondering for both. My guess would be that cooked food would be much safer in streets than raw food. but just a guess.
