Research – Microbiological Quality and Antibiotic Resistance of Relevant Bacteria from Horsemeat
Abstract
The aim of this work was to assess the microbiological safety and quality of horsemeat. A total of 19 fresh horsemeat samples were analysed. Mesophile counts were 4.89 ± 1.08 log CFU/g, and Enterobacteriaceae, Staphylococcus spp., and enterococci were only isolated from 36.84%, 21.05%, and 15.79% of the samples, respectively. Neither Staphylococcus aureus nor Escherichia coli were found in any sample. Listeria spp. and Listeria monocytogenes were detected in 31.58% and 21.05% of the samples, respectively. Campylobacter jejuni was not detected in any sample. The dominant bacteria were lactic acid bacteria. Seven different Staphylococcus spp. were identified, the most common being S. delphini, S. saprophyticus, and S. warneri. S. delphini showed resistance against mupirocin and cefoxitin. All the L. monocytogenes strains showed resistance against ampicillin, cefotaxime, and oxacillin. Multi-resistant Yersinia enterocolitica, Stenotrophomonas maltophilia, and Vagococcus. fluvialis strains were found, with resistance to 11, 7, and 8 antibiotics, respectively, causing significant concern. Therefore, specific actions should be taken to decrease the contamination of horsemeat.

Research – Enhancing microbial control in poultry processing: A comprehensive study on carcass washing systems
In the poultry industry, the evisceration stage often sees the highest microbial load on chicken carcasses. While manual trimming has traditionally been employed to remove gastrointestinal contamination, Brazilian legislation allows the use of a carcass washing system as an alternative. This study aimed to establish and validate a protocol for the use of a chicken carcass washing system as a replacement for manual trimming in a major poultry processing facility in southern Brazil. The methodology followed international standards for microbial analysis such as total mesophilic counts and Enterobacteriaceae. Comparing contamination levels before and after treatments, significant reductions are seen. Manual trimming reduced contamination by 39.43% (gastric), 53% (fecal), and 50% (biliary). Washing achieved greater reductions, with a 96.37% drop in gastric contamination and complete elimination (100%) of fecal contamination. These results met statistical significance. Both procedures reduced contamination levels. Manual trimming maintained 50% of samples below the mean value without exceeding upper control limits (UCL). Washing increased the percentage of samples below the mean value from 46% to 54%, demonstrating its superior efficiency. For Enterobacteriaceae, trimming maintained 44% of samples below the mean value, and washing increased it from 46% to 48%. In conclusion, the carcass washing system effectively removes visible gastrointestinal contents, meeting regulatory standards and receiving authorization from the Federal Inspection Service for use in the facility.
Research – Microbial community structure of plant-based meat alternatives.
A reduction in animal-based diets has driven market demand for alternative meat products, currently raising a new generation of plant-based meat alternatives (PBMAs). It remains unclear whether these substitutes are a short-lived trend or become established in the long term. Over the last few years, the trend of increasing sales and diversifying product range has continued, but publication activities in this field are currently limited mainly to market research and food technology topics. As their popularity increases, questions emerge about the safety and nutritional risks of these novel products. Even though all the examined products must be heated before consumption, consumers lack experience with this type of product and thus further research into product safety, is desirable. To consider these issues, we examined 32 PBMAs from Austrian supermarkets. Based on 16S rRNA gene amplicon sequencing, the majority of the products were dominated by lactic acid bacteria (either Leuconostoc or Latilactobacillus), and generally had low alpha diversity. Pseudomonadota (like Pseudomonas and Shewanella) dominated the other part of the products. In addition to LABs, a high diversity of different Bacillus, but also some Enterobacteriaceae and potentially pathogenic species were isolated with the culturing approach. We assume that especially the dominance of heterofermentative LABs has high relevance for the product stability and quality with the potential to increase shelf life of the products. The number of isolated Enterobacteriaceae and potential pathogens were low, but they still demonstrated that these products are suitable for their presence.

Research – Preliminary Investigation towards the Use of Infrared Technology for Raw Milk Treatment
Abstract
Infrared (IR) technology offers a promising solution for reducing microbiological loads in various food types while preserving their quality traits, such as flavour. However, research on IR’s application in complex matrices is limited. Therefore, our preliminary study aimed to evaluate its effectiveness in sanitizing bovine raw milk. We assessed the bacterial count before and after IR treatment by comparing volatile organic compound profiles via headspace extraction and GC/MS analysis. Our findings showed that higher energy levels led to a greater bacterial reduction. IR85 was the most effective in reducing Coliforms and Enterobacteriaceae in non-homogenised samples, with a reduction ranging from −1.01 to >−2.99 and from −1.66 to −3.09 Log CFU/mL, respectively. IR60 and 70 showed no efficacy, while IR80 had intermediate but still satisfactory effect. IR85 notably affected volatile compounds, particularly increasing hexanal (from 0.08 to 4.21 ng g−1) and dimethyl sulphone (from 10.76 to 26.40 ng g−1), while IR80 better preserved the aroma profile. As a result, only IR80 was tested with homogenised raw milk, demonstrating significant bacterial reduction (from >2.39 to 3.06 Log CFU/mL for Coliforms and from 1.90 to >2.45 Log CFU/mL for Enterobacteriaceae) and maintaining the aroma profile quality.
