A practical and representative sampling method for microbiological examination of the slaughter process is useful for identifying abattoir-specific risk factors within the pig slaughter line. The aim of this study was to examine the suitability of an agar contact method (ACM), where the agar was homogenized before the microbiological processing, in comparison with the wet-dry double swabbing method (WDSM) for quantitative determination of total viable counts (TVC) on pig skin surfaces. In our experimental trial, pig skin pieces were artificially contaminated at 2 levels (3 log and 7 log cfu/ml) with a suspension of bacteria species commonly found on pig skin and cultivated in vitro. Within our field trial, pig carcasses were investigated at pre-chilling in an abattoir under standard processing conditions. For both sampling methods, TVC was determined, and statistical equivalence tests were calculated. Linear regression models showed the similarity of the sampling methods, with coefficient of determination (R2) > 90% and slope parameters of nearly 1 for both trials separately. Statistically significant equivalence between the 2 sampling methods was proven in both trials (with p < 0.0001 within an equivalence range of ± 0.5 log cfu/ml, respectively). The field trial revealed TVC on carcass surfaces sometimes at or below the lower detection limit for the ACM, while TVC from all carcasses were able to be determined by WDSM. Overall, low contamination levels were less reliably detectable by ACM than by WDSM. The ACM can be seen as an additional and suitable sampling procedure for pig skin and can contribute to the identification of abattoir specific risk factors for investigations of the hygienic status at process stages along the pig slaughter line.

Exposure to pesticide spray drift during the application of plant protection products (PPP) in orchards poses potential health risks to bystanders and residents. To address this concern, this study aimed to gather novel field data on exposure to spray drift in orchards. The research was conducted by the Julius Kuehn-Institute (JKI), the Federal Office of Consumer Protection and Food Safety (BVL), and the German Federal Institute for Risk Assessment (BfR). From 2018 to 2021, the method for conducting the field trials and analysis was implemented. The data from multiple series of performed field trials conducted between 2021 and 2022 allowed for collecting data on potential dermal exposure (PDE), inhalation exposure, and ground sediment. The trials considered various distances from the treatment area and drift-reducing techniques. Adult and child mannequins were used to simulate bystanders’ exposure, and petri dishes were used to measure ground sediment. The results showed that drift reduction settings (75% drift reduction) considerably reduced exposure levels on the mannequins. Furthermore, a strong correlation between PDE values for adults and children located next to each other at the same distance was observed. This finding suggests a possibility to convert exposure results from adult to child mannequins. The study produced realistic exposure data for bystanders and residents next to a treated area. It contributes to a better understanding of exposure risks from PPP application and includes data for different distances and spray drift reducing technique. If taken into account for further development of the current risk assessment models, new risk management options for the safe application of PPP, including buffer strips or application of drift reducing systems, might be available in near future.

In the highly automated processing in broiler abattoirs, some process steps reduce the bacterial counts and inactivate or remove pathogens, while others can lead to an increase. The present study compared the reduction of Enterobacteriaceae counts (EBCs) on breast skin samples in 3 broiler abattoirs using different scalding techniques: (A) conventional immersion scalding (360 s), (B) conventional immersion scalding with thermal treatment of the water (204 s), and (C) the AeroScalder® using hot, humid, saturated air as the scalding medium (360 s in air). In 3 commercial broiler abattoirs in Germany and The Netherlands, a total of 320 breast skin samples per abattoir (before and after scalding, after plucking, before and after chilling) and water samples from the scalders were taken and examined for EBC. After scalding, a significant EBC reduction by 0.7 log was determined only for the conventional immersion scalder (Abbatoir A); the reductions of the other 2 scalders were 0.1 log (Abattoir B) and 0.2 log (Abattoir C) and not statistically significant. The EBCs after scalding differed by up to 0.5 log cfu/g when the 3 scalders were compared, and these counts can be seen as similar. For all 3 abattoirs, the largest EBC reductions (p < 0.001) of 2.8 to 3.6 logs were found after plucking. Compared to the immersion scalders, EBCs in water samples were lowest in those taken from the AeroScalder®. Hence, we conclude that the conventional immersion scalders and the AeroScalder® reduced EBCs in a comparable manner. However, the greatest reductions in EBCs were seen after the plucking steps in the studied abattoirs, not after the scalding as such.

Abstract The microbiological status of 10 raw plant-based ground meat products was assessed to obtain insight into contamination levels and the types of bacteria present in these meat analogues. The total bacterial counts at the end of the best before date varied greatly from below 1.0 log 10 CFU/g to 8.31 log 10 CFU/g, while the median count was 3.89 log 10 CFU/g. For each product, the lactic acid bacterial counts were similar, although generally between ca. 0.5 and 1 log 10 lower than the total bacterial counts, indicating that lactic acid bacteria were a majority in the microbiota of these products. While the median counts of toxigenic pathogens were generally very low (< 1.0 log 10 CFU/g), the maximum counts detected in some samples could reach up to ca. 3.0 log 10 CFU/g for presumptive Staphylococcus aureus and Bacillus cereus. No Listeria monocytogenes colonies were obtained in this investigation; however, other Listeria spp. were detected. Thus, the results show that a (re)contamination of these products by pathogenic bacteria can be a potential safety concern. Furthermore, the detection of presumptive B. cereus and the isolation of various Clostridium species from these products indicates that spore-formers may have survived the food processing and therefore, could pose a safety concern, which should be assessed in further studies.
