The objective of this work was to evaluate the quality of informally commercialized raw milk in the city of Itaqui, RS. Various producers provided a total of 21 samples of milk, which were then identified and investigated for fraudulent compounds (chlorine, hypochlorites, hydrogen peroxide, formaldehyde, acid neutralizers, starch, urine, and sucrose), physical-chemical analysis [density, fat content, total dry extract, solids-non-fat, protein content, and titratable acidity], microbiological analysis, antibiotic residues, and somatic cell count (SCC). In the results, sample 8 showed the presence of acid neutralizers. Samples 7 and 15 presented density values in disagreement with the current legislative standards. With regard to the fat content, 33.3% of the samples did not meet the requirements of the Normative Instruction 62/2011, as well as 57.1%, 61.9%, and 61.9% of the samples presented values of SCC, ESD, and acidity that exceeded the allowed parameters, respectively. Considering the total count of microorganisms, 61.9% of the milk samples showed a value greater than that allowed by the standards of legislation. In addition, it was found that 23.8% of the samples contained antibiotic residue. Therefore, it was observed that all of the milk samples presented with at least one parameter in disagreement with current Brazilian legislation.
