    This descriptive and cross-sectional study aimed to determine the concentration of nitrites and nitrates in sausages sold at the La Unión Market, San Juan de Lurigancho, from October to December 2018. The spectrophotometric method at 538 nm was employed. The results showed that the average nitrite concentrations in the fresh (116.48 ± 3.58 mg/kg) and refrigerated (114.77 ± 3.3 mg/kg) sausage groups did not exceed the limits established by the Codex Alimentarius (125 ppm) and INDECOPI (200 mg/kg). However, the fried sausage group (166.58 ± 19.51 mg/kg) exceeded the Codex Alimentarius limit. Regarding nitrate concentrations, the fresh sausage group had an average of 453.63 ± 18.48 mg/kg, which did not exceed the INDECOPI limit (500 mg/kg). In the refrigerated sausage group, the Tuxa brand (511.98 ± 3.11 mg/kg) exceeded the established standard, as did the fried sausage group, Otto Kunz brand (509.47 ± 0.99 mg/kg). In conclusion, nitrite concentrations in the fried sausage group exceeded the limit, as did nitrate concentrations in the Tuxa brand for the refrigerated group and the Otto Kunz brand for the fried group.
