Veterinary and sanitary assessment of livestock farming products manufactured by “Zhytomyr Meat Factory” LLC according to quality and safety indicators

Abstract

Providing the population with high quality and safe products is an extremely topical and global
problem as there is the deficit of high quality raw products in many countr ies of the world and
Ukraine. Therefore the purpose of our studies was to conduct veterinary and sanitary assessment of
livestock farming products manufactured by “Zhytomyr Meat Factory” LLC according to quality and
safety indicators. To solve the problem we conducted the analysis of the reporting documentation for
the period of 2021, veterinary and sanitary expert examination of slaughter products. Meat and byproducts
samples were selected from healthy animals and after rejecting because of invasion and n oncontagious
diseases. Microbiological analyses were made in the bacteriological laboratory of the
state establishment “Zhytomyr Regional Laboratory Center of the Ministry of Health Protection of
Ukraine”. It has been established that invasion and non-contagious diseases causing the worsening of
sanitary quality and biological value were the reasons for rejecting by-products. The udder was
condemned most often (42.7 %) because of mastitis, then came the lungs (26.8 %) as a result of
pleurisy, pneumonia, and blood aspiration. The liver was rejected less for the reasons of fascilosis
and toxic dystrophy. Mesophilic aerobic and facultative anaerobic bacteria index (MAFAnB) of the
liver cleaned out as a result of fascilosis is 86.0 % higher and by 91 % higher because of toxic
dystrophy than in the same organ received from healthy animals. The microbial contamination and
biological value of obtained slaughter animal products is in direct dependence on the degree of their
helminthes’infestation, which is necessary to take into account while conducting veterinary and
sanitary assessment. According to safety indicators (microbiological, antibiotics, mycotoxins,
pesticides, radionucleids, and toxic elements) all products (frozen beef by-products of the first and
second categories, beef in half-carcasses and cooled trimmed beef as well as frozen beef crude fat)
manufactured by “Zhytomyr Meat Factory” LLC correspond to the specification and are safe for
consumers. The amount of mesophilic aerobic and facultative anaerobic microorganisms (clumpcreating
units (CCU) in 1 g), bacteria of E. coli group (BECG – coli-forms), pathogenic
microorganisms including salmonellas (in 25 g) and L. monocytogenes (in 25 g) in all meat samples
selected in “Zhytomyr Meat Factory” LLC were within standard requirements.. Following the proper
hygienic and production practices, using HACCP system of managing the safety of slaughter products
at the enterprise and risk control ensure the obtaining of high quality and safe products. The necessity
of strengthening measures to prevent invasion and non-contagious diseases on the part of veterinary
medicine specialists was determined.
