The objective of this study was evaluated the possible health risks associated with the content of heavy metal and microorganisms in the alfalfa (Medicago sativa L.) juice. Thirteen samples from 33 different markets of Quito-Ecuador were purchased f and analyzed the commercial quality (soluble solids pH, titulable acidity, relative density and humidity), heavy metal (lead, cadmium, copper, chromium and nickel) and microorganism (Aerobic mesophiles and parasites). The results showed that the concentration of lead ranged between 1.40 to 2.49 ppm. These exceeded the maximum limits allowed by CODEX. In addition, in most cases cadmium (0.07 ppm) and copper (0.47 ppm) did not exceed the allowable limits, while chromium (traces) and nickel (0.52 ppm) did not have regulations for their respective comparison. On the other hand, the microbial quality of most of the samples of alfalfa juice showed contamination with mesophilic aerobic microorganism (3.50E+03 UFC/g) and parasites (positive). These finding provide valuable information that can funding food safety decisions, and confirm that the vast majority of vegetables available on Quito’s markets present a problem in terms of bacteriological hazards and heavy metal.
