FIELD: food industry.
SUBSTANCE: method involves bioprobe sampling and its pre-processing by a compression method or a method of digestion in simulated gastric fluid and larvae number calculation with microscope usage. Bioprobes are represented by commercial size salmonids kidneys. The calculated number of larvae in the bioprobes is doubled to obtain intensity of contamination of the zooid under study.
EFFECT: usage of proposed method allows to enhance validity of contamination determination results combined with study process simplification and labour intensity reduction.
