N2 - Rhizoprionodon longurio is an important commercial species captured in an area with heavy metal presence due to the mining waste from Santa Rosalia, Gulf of California, and levels of heavy metals in its muscle remain unknown. This study aimed to investigate whether contamination levels are below the limits allowed for human consumption and to prevent health damage. Concentrations of essential (Cu, Fe, Mn, and Zn) and non-essential (Ag, Cd, and Pb) trace elements were determined in fifty-seven muscle samples of R. longurio. The average concentrations of Fe > Zn > Cu > Mn > Cd > Ag did not exceed the permissible limits for human consumption established by the Mexican norm, WHO, and FAO. The mineral daily ingestion was 0.10 to 0.53 % × 100 g of muscle, and the percentage of weekly consumption was 2.5 % to <12 % concerning corporal weight. The meat from this shark can be consumed due to its low toxic potential for human health.
