Antimicrobial detection from antimicrobial residues in raw milk from dairy farms in western Santa Catarina

Resumo

Milk is a food rich in nutrients, which makes it widely consumed in Brazil. Its quality is vital for the safety of consumers. Antimicrobial residues may be present in milk if proper management is not performed in administering veterinary drugs to treat dairy cattle, thus representing a risk to human health and generating losses in manufacturing dairy products. Therefore, this study aimed to evaluate the presence of antimicrobials in in natura milk samples from rural properties located western Santa Catarina State using Delvotest® T. Milk samples were collected from October to December 2021. Of the 55 samples collected, 9.1% tested positive for antimicrobial residues, pointing to the need for greater control in the process of antimicrobial administration and control of the waiting period and periodic laboratory analysis. The study allowed one to detect antimicrobial contamination in the sampled milk and emphasized the importance of monitoring and controlling the use of these antimicrobials in rural properties to ensure food safety.
