MONITORING OF RESEARCH ON BOVINE SPONGIOFORM ENCEPHALOPATHY IN THE CONDITION OF THE VINNYTSIA REGIONAL STATE LABORATORY OF SSUFSCP
Abstract
Ukraine is included in the third category of countries that have an official status according to the BSЕ – a country with an uncertain risk. This is the main reason for the impossibility of exporting red meat to EU countries. The state is working on obtaining the status of a country with a controlled risk for BSЕ, which will allow Ukraine to trade ruminants of certain age categories and products obtained from them. The official components of obtaining the status are legislation and an annual risk assessment, which includes observation and monitoring. Post-mortem material (oblong brain) from cattle older than 24 months, obtained in 2021-2023, was used for research and frozen for storage. Monitoring studies of cattle older than 36 months on GE in the case of slaughter under normal conditions requires receiving at least 300,000 points in 7 years – respectively for a country with an uncertain status regarding GE, namely Ukraine. Livestock arrived for slaughter in Vinnytsia from various regions of Ukraine for three years and were examined in the conditions of the Vinnytsia Regional State Laboratory of the SSUFSCP. Prion tests approved by the European Union and recommended by the International Epizootic Bureau are used for monitoring studies as quick methods for identifying patients with BSЕ. A study was conducted on BSE in the case of slaughter under normal conditions in the Vinnytsia Regional State Laboratory of SSUFSCP for the past three years of samples of material from 22562 animals, as a result 3104 points were obtained, of which the largest number was from animals of the Vinnytsia region 1147 points (37%), slightly less 745 points (24%) from animals of the Cherkasy region, 512 points (17%) from other regions except Kyiv, Khmelnytskyi and Zhytomyr regions.
