Abstract
Biosensors provide analysis with high sensitivity and selectivity associated with portability and easy handling compared with the traditional methods. These devices have gained interest in the scientific field with application in the agroindustry, mainly in the dairy farming sector, because of their possible use to detect antibiotic residues used to treat mastitis and dry cow therapy. The use of antibiotics for this sector is estimated at 63.000 tons/year, and biosensors can be a viable alternative in the detection of such contamination in the milk, to alert the producers regarding the contamination level in loco, and thus reducing the indiscriminate use and the risk for the consumer. Therefore, this work presents a review of the main proof-of-concept biosensors applied in dairy farming in the past ten years, seeking to improve the discussions regarding the implications of antibiotic use in cattle and their consequences in humans.
