Development of an analytical method for the analysis of diflubenzuron in whole blood, plasma, and serum using liquid chromatography tandem mass spectrometry.

The integration of free-range beef livestock into the human food chain has been continuously threatened by outbreaks of babesiosis, which is propagated by ticks that vector the protozoans that cause the disease. The protozoans are spread among livestock by certain species of ticks, known collectively as cattle fever ticks (CFT). Although eliminated from the US in the 1940s, CFT continue to infiltrate the US by crossing the US/Mexico border on stray livestock and wildlife, and infest cattle herds.
