The aim of the study was to investigate the microbiological and physico-chemical quality of honey samples, sampled for the event “Honey Days in FB&H 2020”, which tested a total of 33 samples of different honey types from different geographical areas of Bosnia and Herzegovina (B&H). The aim of this study was to evaluate the relationship between physico-chemical properties and microbiological properties of the tested honey to assess quality. The submitted samples originated from both administrative units of B&H, namely from the continental, sub-Mediterranean and Mediterranean part, covering more than 60% of the country’s territory. Of the total number of analysed samples (n=33), nine samples (29.7%) did not meet the requirements of physico-chemical and microbiological parameters of the test. The requirements of one or more quality parameters according to the national Ordinance on methods for the control of honey and other bee products in B&H (Anonymous, 2009) were not met by five samples (16.5%). Four samples (13.2%) did not meet the microbiological quality, as they exceeded the permitted number of yeasts and moulds. In five samples (16.5%), the presence of microorganisms was recorded within the tolerance limits, while Enterobacteriaceae and sulphite-reducing clostridia were not isolated and were below the detection limit in all samples. Honey samples in which the results were found to be unsatisfactory for physico-chemical parameters and microbiological parameters cannot be correlated.

the aim of this study was to determine the effect of sex and age at slaughter on the physicochemical properties and quality of Simmental baby-beef. the research was conducted on 1,200 livestock, of which 600 were male and 600 female. Male cattle were slaughtered at the age of 13 to 14 months, 15 to 16 months and 17 to 18 months, while female cattle were slaughtered at the age of 12 to 13 months, 14 to 15 months and 16 to 17 months. Physicochemical properties associated with the quality of meat (ph, eC and meat colour parameters) were measured 24 hours post mortem on the m. longissimus dorsi. While sex significantly influenced the physicochemical properties associated with the quality of baby-beef (P<0.001), different age at slaughter had little effect on the physicochemical properties associated with the quality of meat (P>0.05), thus indicating the possibility of increasing the slaughter age of male and female Simmental cattle up to 18 and 17 months respectively, without a substantial negative impact on the physicochemical properties associated with the quality of baby-beef.

In this study, the presence of Listeria monocytogenes was assessed along the production process of fermented sausages in a small-scale facility. Following the isolation of the pathogen from the final product (ISO 11290-1), retrospective sampling was performed during the production of a new batch of sausages, including raw materials, casings, additives, sausage mixtures, sausages during fermentation, and environmental samples. L. monocytogenes was recovered from the following sampling points: the defrosting room and the cuttering, mixing, stuffing, and fermentation phases. Ten strains were isolated, molecularly confirmed as L. monocytogenes by means of a molecular detection system, and subjected to pulsed-field gel electrophoresis (PFGE) typing. On the basis of an unweighted pair group method with arithmetic mean (UPGMA) dendrogram from Ascl pulsotypes, the strains were indistinguishable (no band difference). The same pulsotypes of strains present in both batches of sausages, as well as in environmental samples, indicated the persistence of L. monocytogenes in the sausage production unit.
