The aim of this study was to determine the potential presence of the airborne Listeria spp. and its correlation with the aerobic mesophilic bacteria and Listeria carcass contamination in three red meat slaughtering and three processing plants. Airborne L. seeligeri and L. innocua were determined using 8 (5.06%, n = 158) air samples taken on the locations characteristic for aerosol generating and in a chilly environment. The positive airborne samples of Listeria spp. were in an insignificant (P &gt; 0.05) relation with the highest airborne bacteria counts. On the carcass, only 1 positive case (0.69%, n = 144) of L. innocua was determined, presumably owing to the low airborne Listeria counts and its unpredictable settling rates. In addition, insignificant (P &gt; 0.05) influences of air moisture and airflow on the airborne Listeria were found. Nevertheles, the methods currently used to determine the airborne Listeria and its relationships to aerosol viable mesophilic bacteria and carcass contamination need to be reconsidered in future investigations.

This work represents and reviews a compilation of investigations into improving anaerobic digestion performance of high-strength wastewater in the Australian Red Meat Processing industry. The industry produces significant quantities of organic-rich wastewater which requires treatment prior to release to the environment. Anaerobic lagoons are a cost-effective method of waste treatment where land availability is not an issue; however, the high fat load in the wastewater can negatively impact the anaerobic lagoon system and result in compromised anaerobic digestion performance. This paper will discuss the importance of upstream primary pre-treatment and review a series of investigations focused on optimising digester performance and improving fat biodegradability. These studies include: 1. the effect of temperature and mixing; 2. the influence of feedstock trace element composition and supplementation, and; 3. the potential benefit from pre-treatments such as chemical, thermobaric, thermochemical and bio-surfactant. This paper discusses the implications of these findings for covered anaerobic lagoon operation and provides recommendations to promote optimum digester performance and future opportunities in adopting alternate anaerobic digestion technology options. Finally, the paper provides recent trends toward the use of other waste streams for co-digestion and discusses this in terms of digester optimization and technology options.

Background. The total production of beef and pork is declining from year to year. The study of development trends in the meat industry of Ukraine will help to outline the prospects for the successful realization of potential opportunities for production expansion. An analysis of recent research and publications has shown that despite some scientific developments, dynamic changes in the meat processing industry require constant monitoring of unresolved issues. The aim of the study is to analyze the current state and characteristics of the meat processing industry of Ukraine on the basis of analytical research in general and in the context of its innovation activities in particular. Materials and methods. Research methods were used: monographic, statistical groupings, correlation-regression analysis, graphical. Results. Analysis of the dynamics of industrial meat production shows that beef and veal occupy the least share in it. The basis for ensuring the economic balance of production and economic relations of economic entities is the consistency of supply and demand for raw meat and products of its processing. For the successful development of the industry, the state must protect and stimulate domestic producers; to harmonize domestic standards of safety and quality of products in accordance with international ones. The innovative development of the meat market requires adequate investment support, and the stimulation of investment activity should be considered in the context of the strategy of development of the national economy on an innovative basis. Conclusion. Livestock production in general and meat in particular are one of the leading sectors of agriculture. In recentyears, there have been some trends in the dynamics and structure of meat production and consumption in favor of cheaper poultry meat. The reason for this is the reduction in production; increase in retail prices for all types of products; low incomes of the majority of the population. A necessary condition for the sustainable development of the meat processing industry is the introduction of European regulations on product quality and safety standards; introduction of resource-saving technologies at enterprises; reconstruction of enterprises; provision of production facilities with domestic raw materials.
