    Book of Abstracts XIX Baltic animal breeding conference, December 14-15, 2022, Tartu, Estonia
    (Estonian University of Life Sciences, 2022) Viinalass, Haldja (compiler); Arney, David (compiler); Tänavots, Alo (compiler); Institute of Veterinary Medicine and Animal Sciences
    Dear colleagues, On behalf of the Organizing Committee, I am pleased to invite you to attend the XIX Baltic Animal Breeding Conference that will be held in Tartu, Estonia, at the Estonian University of Life Sciences from December 14-15, 2022. The recent pandemic has shown us that our sector never stops, that animal production continues to produce food for us and that we are an essential part of society. In 2022 we will surely be under the economic and societal consequences of this pandemic and the changed situation in the world. This year’s Baltic Animal Breeding Conference is already the 19th. The Baltic Animal Breeding Conference, which has taken place over the years, will give us an opportunity to exchange information and new ideas, and will encourage the development of further fruitful collaboration and networking. The conference will present ideas of what animal husbandry researchers and lecturers in the Baltic countries are currently doing. The conference is planned in a traditional way: a plenary session in the morning and a species session in the afternoon on December 14th , followed by a technical tour on December 15 th . The programme will cover various areas of animal production and the topics will be filled with innovation and recent scientific results in animal production. As a community, we must make up for the lost opportunities for face-to-face networking. Happy listening, nice meetings and flying ideas! Prof Haldja Viinalass, Chair of Organizing Committee

    Extracellular vesicles (EVs) are released by cells and have a lipid bilayer structure. EVs harbor various molecules, including proteins, RNAs, and DNAs. Studies of mammalian EVs are increasingly attracting the interest of researchers; however, there are only few studies of nanoparticles in food. Milk-derived EVs can survive high temperatures and digestion process, while retaining their biological activity. This study investigated the effect of pasteurized cows’ milk derived EVs on growth of five different bacteria. Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 53868, Bacillus subtilis, Bacillus cereus and Pseudomonas aeruginosa with a concentration of 1x107 CFU/ml were separately co-cultured with pasteurized milk derived EVs (1x109 EVs/μl) in Muller Hinton broth. The bacterial growth was monitored as absorbance at 620 nm over 24 hours. Bacteria treated with phosphate buffer solution (PBS) were considered negative control throughout the experiment. The percentage bacterial growth difference was COMBIVET & OH-BOOST JOINT CONFERENCE 2023 55 determined with respect to negative control and results expressed as mean ± standard error of mean. All analyses were performed in three biological triplicates and each biological replicate consisted of three technical replicates. Co-culture of bacteria with milk EVs demonstrated that EVs could decrease the growth of S. aureus, B. subtilis, B. cereus and P. aeruginosa. Highest growth inhibition was observed for B. subtilis (33.9% ± 2.4) followed by B. cereus (18.1% ± 3.7) at 6 hours of incubation. S. aureus and P. aeruginosa growth were inhibited by 12.9% ± 1.3 and 9.9% ± 3.5 respectively after 9 hours incubation. Only the S. aureus growth inhibition at 9 hours was statistically significant (P=0.022) according to T-test. However, E. coli growth was not affected by milk EVs compared to the control. In conclusion, the dietary EVs can be absorbed by bacteria and pasteurized milk derived EVs has a selective inhibitory activity on the growth of some bacteria.

    Growth potential of L. monocytogenes in ready-to-eat minced meat samples enriched with plant powders
    (Faculty of Pharmacy, University of Helsinki, 2023) Koskar, Julia; Roasto, Mati; Meremäe, Kadrin; Elias, Terje; Mäesaar, Mihkel; Rätsep, Reelika
    Listeriosis is the fifth most frequently recorded human zoonosis in the European Union and one of the most serious foodborne diseases. Regulation (EC) No 2073/2005 lays down the microbiological criteria for Listeria monocytogenes in ready-to-eat (RTE) foods. In case a food business operator wants to apply the numeric criterion of 100 cfu/g to RTE food, a challenge test needs to be performed in accordance with the European Union Reference Laboratory for Listeria monocytogenes (EURL Lm) technical guidance document on challenge tests and durability studies regarding L. monocytogenes. The aim of this research is to provide an overview of the possibilities of inhibiting the growth of L. monocytogenes in minced meat products enriched with plant powders.
