    This was a descriptive, cross-sectional, and prospective study conducted in the El Huáscar and El Bosque food markets in the district of San Juan de Lurigancho, Lima, Peru. Its objective was to determine the concentrations of nitrites and nitrates present in artisanal sausages sold in these markets, given their toxic effects on health, such as methemoglobinemia and the formation of carcinogenic nitrosamines. The concentrations of these additives were determined using spectrophotometric analysis and then compared with the quantities established by current national (Indecopi) and international (Codex Alimentarius) regulations. The analytical method was based on Peruvian Technical Standard ISO 2918:2006 for nitrites and Peruvian Technical Standard ISO 3091:2005 for nitrates. In the 25 samples analyzed, the nitrite concentrations in the El Huáscar and El Bosque markets were 116.87 mg/kg and 166.93 mg/kg, respectively, while the nitrate concentrations were 451.18 mg/kg and 458.06 mg/kg, respectively.
