-- This is a cross-sectional and descriptive study conducted in 23 state educational institutions in the district of Villa El Salvador, with the aim of determining concentrations of nitrites and nitrates in hot dogs that are sold for direct consumption in these educational institutions, because of their known toxic effects on health, such as methemoglobinemia and formation of carcinogenic nitrosamines. For this purpose, it was determined the concentrations of these additives in samples of hot dog in the 23 schools through spectrophotometric analysis on a Spectronic - G Bauch and Lomb, and then compared these values with the quantities established by national (INDECOPI) and international (Codex Alimentarius) regulations nowadays. The analytical method is based on the Peruvian Technical Standard ISO 2918:2006 for the case of nitrite and the Peruvian Technical Standard ISO 3091:2005 in the case of nitrate. The values found for nitrites and nitrates in the 23 samples analyzed varied in a range from 122 ppm to 399 ppm and 482 ppm to 738 ppm, respectively, and average concentrations of nitrite in the case is 176.96 ppm and for the case of potassium nitrate is 530.31 ppm. In parallel, we determined the percentage and frequency of consumption of hot dogs in the students of fifth and sixth grade primary educational institutions themselves by conducting a weekly consumer survey, which indicates that 55.4% the students themselves consumed hot dog at school, while the frequency of consumption occurs mostly once a week mainly in the stores of state educational institutions. Therefore concluded that the concentrations of nitrites and nitrates present in samples of hot dogs in the 23 state educational institutions in the district of Villa El Salvador exceeds the maximum permissible levels given by the Codex Alimentarius and INDECOPI respectively and the rate of consumption students in grades 5 and 6th grade of primary education is also high. -- Key Words: meat products, nitrites, nitrates, hot dogs, toxicological analysis.
