Veterinary-sanitary examination of offal obtained from of sick animals

Abstract

Substandard offal can be a danger to human health, so it is important to objectively carry out veterinary and sanitary control at all stages of circulation of these products. Veterinary-sanitary examination of offal in accordance with the rules of veterinary inspection of slaughter animals and veterinary-sanitary examination of meat and meat products is obligatory together with carcasses. The conventional methods of postslaughter examination allow to reveal of pathoanatomical changes which characterize of infectious and invasive animal diseases and make it possible to establish a preliminary diagnosis. However, laboratory analysis should be done in the absence of obvious macroscopic changes in offal intended for food purposes and obtained from sick or dead animals in the agricultural state, or after their industrial processing and also is required to confirm the quality and safety of livestock raw materials. Veterinary-sanitary examination of offal obtained from the forced killed calves with clinical diagnosis - pneumonia by the methods regulated by the existing normative and technical documents was carried out. In the same way as in the meat of sick animals, in heart, liver, lung, kidney and spleen of slaughtered animals peroxidase wasn’t shown, revealed the primary products of protein breakdown in the sample with formalin, and observed the increase in hydrogen ion concentration in the extract of the samples. The transparency of the broth obtained during the production of samples of cooking depends on the type of offal of raw materials and the assessment of the purity of the liver, spleen and lungs is not significant, however, the smell of the broth from the offal derived from infected animals significantly decreases, compared to the specific smell of the broth from the offal derived from healthy animals.
