The contamination of hydrobiological species in our rivers by heavy metals is a serious and concerning issue, as it endangers the lives of these species and the populations that consume them. Objective: This research aims to determine the concentration of arsenic, chromium, cadmium, and lead in shrimp (Cryphiops caementarius) and the potential health risks for the population of Calango and Santa Cruz de Flores during the period from April to October 2020, due to exceeding the maximum permissible limits according to Brazilian Legislation and the Codex Alimentarius standards. Methodology: This was a quantitative, descriptive, basic-level study with a non-experimental, cross-sectional research design. Atomic absorption flame spectrophotometry and a hydride generator were used. Results: Shrimp samples were collected along the Mala River at 3 points in the Santa Cruz de Flores area and 7 points in the Calango area, for a total of 10 sampling points. The average values obtained were 0.89 mg/kg for arsenic, 0.040 mg/kg for chromium, 0.24 mg/kg for cadmium, and 0.44 mg/kg for lead in the shrimp samples from the designated points. These values did not exceed the maximum permissible limits set by international regulations, including Brazilian Legislation and the Codex Alimentarius, during 2020. Conclusion: The consumption of shrimp was not considered a public health risk for any of these heavy metals—cadmium, chromium, lead, and arsenic. However, due to the values found in the upper range, continuous monitoring of these metals' concentrations in these areas is recommended.
