Abstract
Information regarding microbiological hazards in edible macroalgae and halophytes is scarce, and standard methods for detecting norovirus in vegetables have not yet been validated for these types of food products. Accordingly, the suitability of the NF EN ISO 15216-2 standard method for macroalgae and halophytes was evaluated using 57 samples collected along the Western coast of mainland Portugal. The presence of Salmonella in 46 samples was also tested to confirm potential hazard. The viral extraction process was validated for 72% of the samples, with results showing that the standard method is suitable for green and red macroalgae, as well as for halophytes. For brown macroalgae, a process optimization should be considered. None of the samples revealed the presence of norovirus genomes, neither genogroups I nor II. Salmonella was detected in one of the samples analysed. The present study shows the great potential of Portuguese coastal areas for marine agriculture.
有关可食用大型藻类和卤叶植物中微生物危害的信息很少,而且检测蔬菜中诺如病毒的标准方法尚未针对这些类型的食品进行验证。因此,我们使用在葡萄牙大陆西海岸采集的 57 个样本,对 NF EN ISO 15216-2 标准方法是否适用于大型藻类和卤叶植物进行了评估。此外,还检测了 46 份样本中是否存在沙门氏菌,以确认潜在的危害。对 72% 的样本进行了病毒提取过程验证,结果表明该标准方法适用于绿色和红色大型藻类以及盐生植物。对于棕色大型藻类,应考虑优化流程。所有样本均未发现诺如病毒基因组,也未发现基因组 I 或 II。在分析的一个样本中检测到了沙门氏菌。本研究表明,葡萄牙沿海地区具有发展海洋农业的巨大潜力。
期刊介绍:
Food Control is an international journal that provides essential information for those involved in food safety and process control.
Food Control covers the below areas that relate to food process control or to food safety of human foods:
• Microbial food safety and antimicrobial systems
• Mycotoxins
• Hazard analysis, HACCP and food safety objectives
• Risk assessment, including microbial and chemical hazards
• Quality assurance
• Good manufacturing practices
• Food process systems design and control
• Food Packaging technology and materials in contact with foods
• Rapid methods of analysis and detection, including sensor technology
• Codes of practice, legislation and international harmonization
• Consumer issues
• Education, training and research needs.
The scope of Food Control is comprehensive and includes original research papers, authoritative reviews, short communications, comment articles that report on new developments in food control, and position papers.
