Description
Stefani Maria Ferreira and co-authors describe a 2026 study of a pest drug poured on cattle skin. The drug kills ticks and flies, and its traces in meat matter for food safety. The team tracked how long the drug and its break-down products stay in blood under farm conditions.
Bulls got one skin dose, and blood was checked for near half a year with a fine lab method. The parent drug peaked on day one and was gone by about five weeks. A sulfone product peaked near two weeks and lasted far longer, up to about twenty weeks. A third product, made by sunlight on the skin, showed up now and then at low levels. The authors name the sulfone as the best safety marker.
