Mushroom alcohol treatment increased the activity of superoxide dismutase in <em>A. tenuissima</em>, promoted the accumulation of superoxide anion and hydrogen peroxide in the early stages of culture, inhibited the activity of catalase and polyphenol oxidase, and disturbed the balance of antioxidant metabolism. Furthermore, mushroom alcohol treatment reduced the activity of dehydroascorbate reductase, monodehydroascorbate reductase, and glutathione peroxidase and decreased the amount of antioxidants, resulting in decreased pathogen resistance. The treatment also damaged the cell membrane structure of <em>A. tenuissima</em>, leading to increased relative conductivity, malondialdehyde accumulation, and extensive leakage of nucleic acids and proteins. After the wolfberry was inoculated with the pathogenic fungus, mushroom alcohol treatment significantly reduced wolfberry disease incidence and lesion area.

This study aimed to explore the feasibility of using CCTV for covert observation to assess hand hygiene compliance. Face-to-face interviews with technical leaders (<em>n</em> = 21) from manufacturing businesses (<em>n</em> = 11) explored the use and benefits of CCTV and investigated perceptions regarding utilising CCTV to assess hand hygiene compliance. Although CCTV systems are common in food manufacturing, findings indicated they were seldom used to observe hand hygiene practices. Cameras were predominantly installed as a crime deterrent or used in the event of incidents, accidents or complaint investigations. Businesses reported a lack of dedicated resources and time to conduct regular structured observations using CCTV systems to establish compliance. CCTV footage (53h) from manufacturers (<em>n</em> = 3) including 852 hand hygiene attempts was reviewed using an electronic observational checklist to determine compliance. Findings indicated that although the majority (88%) of food handlers attempted to implement hand hygiene practices prior to entering food production areas, almost all attempts (98%) were non-compliant with hand hygiene protocols. This study concludes that the widespread use of CCTV systems, providing multiple vantage points throughout food manufacturing facilities, allows for unobtrusive observation of food handler behaviours. The study has determined the feasibility of using covert observation to assess hand hygiene compliance in food manufacturing businesses to identify practices that require further direct remediation or intervention.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"175 ","pages":"Article 111282"},"PeriodicalIF":5.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper was written by members of RIBMINS, a Europe-wide network of food safety researchers, with the aim to review the existing economic evidence on interventions to curb <em>Salmonella</em> spread in animal-derived food systems. Despite the widespread implementation of national control plans our search yielded only 35 primary sources of data over the span of 40 years and multiple value chains. Cost-benefit analyses were the most frequent type of study. There was little consistency between the variables included in these analyses thus hindering potential comparisons. Much of the identified literature was focused on interventions at the farm level (n = 24) either exclusively or associated with further interventions in the value chain such as at harvest and/or feed production. From the data, it became apparent that most of the costs are borne by the private sector which is not surprising given the potential for outbreaks to damage reputation and profitability. On the other hand, the most benefit is accrued by the public sector through decreased health costs and improved workforce productivity. We argue that to be able to make evidence-based decisions on which <em>Salmonella</em> control interventions to adopt and where the cost of these should fall, standardised economic analysis should be undertaken in the food safety space.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"175 ","pages":"Article 111275"},"PeriodicalIF":5.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a growing need for simple and cost-effective methods of neomycin detection. This study presents the development of an electrochemical aptasensor for neomycin detection in cow's milk.

The developed electrochemical aptasensor exhibits high sensitivity and a low detection limit (36.3 nM in a 10-fold-diluted cow's milk sample), and selectivity for neomycin over structurally similar compounds (kanamycin and streptomycin) as well as antibiotics from tetracycline group (tetracycline and oxytetracycline).
