The ability of Anisakis larvae (AL) isolated from frozen poutassou trunks to cause allergic and toxic effects on non-linear male rates during feeding was studied. For 10 days animals divided into 4 groups received AL at the dose: 100 individual/head (group 1), 50 individual/head (group 2) and 10 individual/head (group 3); group 4 was control. Hematological and biochemical blood investigations have found acidophilia, increased total protein, AlAt and AcAT, creatinine and alkaline phosphotase at day 3, 5 and 10; histological investigations – dystrophic changes in livers and jejunitis. Therefore, treating fish with low temperatures preserves excretory, secretory and somatic products of frozen larvae causing am allergic reaction the intensity of which (acidophilia) directly depends on AL dosage. The pattern of biochemical parameters points out to toxic damage of livers and intestines. It is concluded that anisakidosis being zoonosis is dangerous for human health, as neither cooking, nor freezing fish reduce a danger of an allergic and toxic effect of AL. Using frozen fish containing AL as a food is also dangerous for health of domestic animals
