在墨西哥等发展中国家，街头食品行业为很大一部分人口提供了就业机会和廉价的即食食品，但人们对其在食源性疾病（FBD）传播中的作用知之甚少。由于其广泛的消费，墨西哥街头出售的辣椒酱是FBD的潜在载体。在墨西哥城进行了一项观察性研究，收集了43种街头出售的辣椒酱。这些酱料在处理和销售时的卫生条件很差。消费者在每个墨西哥卷饼中加入4-8毫升辣椒酱，每餐摄入2-5个墨西哥卷饼，平均每天有50名消费者光顾一个摊位。17份（40%）样品被粪便污染，2份（5%）酱汁含有足以致病的产肠毒素大肠杆菌。我们估计，每年仅食用其中一种辣椒酱就可能导致至少21000名消费者患ETEC病，使他们成为FBD的重要潜在载体。
The street-vended food industry provides employment and cheap ready-to-eat meals to a large proportion of the population in developing countries like Mexico, yet little is known about its role in the transmission of food borne diseases (FBD). Because of its wide consumption, street-vended chili sauces in Mexico are potential vehicles of FBD. An observational study was performed in Mexico City collecting 43 street-vended chili sauces. These sauces were prepared under poor hygienic conditions of handling and selling. Consumers add 4-8 ml of chili sauce per taco, ingest 2-5 tacos per meal and on average, 50 consumers frequent a stall per day. Seventeen (40%) samples were faecally contaminated and 2(5%) sauces harboured sufficient enterotoxigenic Escherichia coli to cause disease. We estimate that the consumption of only one of these chili sauces could result in ETEC disease in at least 21000 consumers per year, making them important potential vehicles of FBD.
