Lateral flow assays to evaluate bacterial and toxic contamination of animal raw materials

Abstract

Abstract The paper presents and analyzes methods for controlling bacterial and toxic contamination in goods subject to veterinary supervision. Using labelled nanometer-sized particles of gold, the method proves to be efficient in rapidly detecting Salmonella, Staphylococcus and Botulinum toxins in meat within 1-4 hours. For the first time, modifications were developed at the stage of sample preparation using Sephadex to concentrate toxins, increasing the detection sensitivity by 2-3 times.
