The materials were 440 street food vendors in China, Thailand, Greece and Poland. Specially designed questionnaire allowed fast data collection. Many non-compliances in the hygienic practices was found. Hygiene requirements in section of hygiene of equipment and food preparation and serving were better implemented than in personal hygiene. In surveyed EU countries, hygiene of equipment and food preparation generally showed higher conformity than in Asian countries.

The level of fulfillment of the hygienic requirements was most strongly influenced by the type of street food vendor, both in the section of personal hygiene and hygiene of equipment and food preparation and serving.
