Nevertheless, their microbiological status, general hygienic and trading practices are not well known. During spring and summer 2000, five <jats:italic>tianguis<\/jats:italic> (open markets) were visited and 48 vendors in 48 stalls interviewed. A total of 103 taco dressings were sampled for <jats:italic>E. coli<\/jats:italic> and <jats:italic>Salmonella<\/jats:italic> spp.: 44 (43%) contained <jats:italic>E. coli<\/jats:italic> and 5 (5%) <jats:italic>Salmonella<\/jats:italic> (2 <jats:italic>S<\/jats:italic>. Enteritidis phage type 8, 1 <jats:italic>S<\/jats:italic>. Agona, 2 <jats:italic>S<\/jats:italic>. B group). Both <jats:italic>E. coli<\/jats:italic> and salmonellas were isolated from three samples. Of <jats:italic>Salmonella<\/jats:italic>-positive stalls 80% (4\/5) had three or more food-vendors and 80% of vendors were males, compared with 37\u00b73% (16\/43) and 46\u00b74% (20\/43) in the <jats:italic>Salmonella<\/jats:italic>-negative stalls respectively. Food-vendors kept water in buckets (reusing it all day), lacked toilet facilities, and prepared taco dressings the day before which remained at the <jats:italic>tianguis<\/jats:italic> without protection for 7\u00b78 h on average. Consumption of street-vended food by local and tourist populations poses a health risk.<\/jats:p>","DOI":"10.1017\/s0950268804003036","type":"journal-article","created":{"date-parts":[[2004,11,16]],"date-time":"2004-11-16T04:24:28Z","timestamp":1100579068000},"page":"1181-1184","source":"Crossref","is-referenced-by-count":43,"title":["Prevalence of <i>Escherichia coli<\/i> and <i>Salmonella<\/i> spp. in street-vended food of open markets (<i>tianguis<\/i>) and general hygienic and trading practices in Mexico City"],"prefix":"10.1017","volume":"132","author":[{"given":"T.","family":"ESTRADA-GARCIA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"LOPEZ-SAUCEDO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"ZAMARRIPA-AYALA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
