Pesquisa de resíduos de antibióticos em leite in natura, pasteurizado e UHT
Resumo:
The presence of antibiotic residues in milk may occur due to their deliberate addition to the animal's feed and the final product or, due to non-compliance with the latency period after administration of these drugs in dairy animals, thus leading to undesirable reactions to humans, such as hypersensitivity, bacterial resistance and imbalance of the intestinal microbiota. Thus, the objective of the research was to investigate the presence of antibiotic residues in fresh, pasteurized and UHT milk samples marketed in the cities of Bela Cruz and Sobral, located in Ceará. Ninety milk samples were analyzed, of which 30 were fresh milk, 30 pasteurized milk and 30 UHT milk. Qualitative analyzes of antibiotic residue detection in milk were performed following the instructions in the Cow Side II Test kit. Of the 90 samples studied, 63.33% were positive for the presence of antibiotics, where 70% of the fresh milk samples, 73.33% of the pasteurized and 46.67% of the UHT milk samples showed positive reaction to the presence of antibiotics. antibiotics. It was concluded that in the majority of the samples studied there was the presence of antibiotic residues and the present residues were not quantified to compare with the acceptable limit due to the qualitative kit used for the tests. It should also be noted that despite the non-quantification, the presence of these residues should still be considered a concern for consumers, as it is known that they can cause allergic reactions in individuals with hypersensitivity, as well as exposing consumers to other serious risks.
Keywords: antibiotics, milk, resistance.
