Based on the results of the existing studies, the main factors that affect consumers’ WTP for GM foods are “product information and labels”. For functional foods, “displaying a health claim, consumers’ awareness and information, variety, and consumers’ trust” are factors that affect WTP. “Consumers’ satisfaction, product logos and price, rural–urban differences, and socio-demographic variables” are factors affect WTP for organic foods. One factor that strengthens consumers in making good choices is better knowledge and information about GM food. Food producers and stakeholders should take the importance of these factors seriously, as they could affect consumers’ WTP.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 1","pages":"3 - 13"},"PeriodicalIF":1.4,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138585262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 (R<sup>2</sup>) > 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 <i>p</i> < 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.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 1","pages":"41 - 48"},"PeriodicalIF":1.4,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-023-01473-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138546728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 2","pages":"131 - 142"},"PeriodicalIF":1.4,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-023-01468-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

In this study, the cornbread-making process using the unit operations nixtamalization with different calcium sources, fermentation, and baking was evaluated as a method for AF detoxification at 2 different contamination levels. The nixtamalized cornbread-making process with tequesquite (an alkaline mineral complex) showed an average reduction of 77.12% in AF content from 550.33 µg/kg to 114.50 µg/kg. For the second contamination level (2208.33 µg/kg), the cornbread-making process with the nixtamalization using calcium hydroxide was the most effective, resulting in an average reduction in AF content of 83.58% (362.50 µg/kg).

Additionally, when the AF extracts of cornbread samples were subjected to acidic pH values (pH = 3), an additional reduction in AF content was achieved. The chemical structure of AFs did transform to irreversible forms, with only non-fluorescent derivatives remaining.
