The Microbes and Food Safety (MFS) ISP will provide an understanding of how microbial threats, such as pathogens and spoilage-causing bacteria, evolve and interact to affect food safety and develop strategies to reduce their impact on health and the economy. We take for granted that most of the food we eat in the UK is free from the risk of microbial pathogens but the Food Standards Agency (FSA) estimates that around 2.4 million cases of microbial foodborne illness occur every year, costing in excess of £9 billion. There is also an economic threat of food waste through spoilage, increasing retail costs; up to 25% of food spoilage is due to the action of microbes. Our mission is to reduce human foodborne illness through improved food safety and to reduce waste due to food spoilage. To do so, we will address key food safety questions in three Themes: 1) what and where are the microbial threats in foods? 2) What are the factors associated with the survival and success of microbial threats? 3) How can we use this information to improve food safety and reduce food waste?Throughout this programme, we will focus on key organisms and issues of strategic importance for food safety, in which we will exploit and further develop our demonstrable expertise. These are Campylobacter, Salmonella, Listeria, Pseudomonas, antimicrobial resistance (AMR) and the identification of emerging microbial threats through the use of metagenome sequencing. As microbial threats such as pathogens and spoilage-causing bacteria exist as complex microbial communities across the food chain, we focus not only on the key organisms of interest, but we will also study the other microbes present which may support their survival or persistence.In Theme 1, MICROBIAL THREATS FROM FOODS IN ESTABLISHED AND EVOLVING FOOD SYSTEMS, we will identify what microbial threats are present in our food - particularly newer food types. Our aim is to understand how microbial threats spread and cause disease or food spoilage by studying the genetic diversity and dynamics of gene flow within populations of foodborne bacteria. In particular we will assess evolving microbial threats from foods associated with shifts in consumer preference, trading relationships and climate change.In Theme 2, MICROBIAL SURVIVAL IN ESTABLISHED AND EVOLVING FOOD SYSTEMS, we will define the factors associated with the survival and success of microbial threats. Our aim is to understand microbial survival and adaptation better by understanding the lifestyle of the bacteria present, e.g. biofilms, community associations and/or metabolism without growth. To do this we will use our specialised core services, including informatics, sequencing and microscopy to investigate samples taken from throughout the food chain and also from human clinical samples.In Theme 3, FLEXIBLE CAPABILITIES TO REDUCE FOOD SAFETY THREATS AND RESPOND TO EMERGING NATIONAL NEEDS, we will use the data generated in the first two themes to improve food safety and reduce food waste. We will work with our stakeholders within QIB, academia, government and industry to apply the scientific evidence derived from our fundamental research to improve the evaluation of future risk and to inform the control of threats to food safety and resilience. Our capability will remain flexible so that we can respond quickly to unexpected emerging national needs as required.Our aim with this programme of work is, with our established stakeholders, to improve the production of safe and nutritious foods and reduce loss of food from spoilage through the delivery of scientific knowledge and acting as a knowledge and training hub for microbial food safety.

微生物和食品安全（MFS）ISP将提供微生物威胁（如病原体和腐败细菌）如何演变和相互作用以影响食品安全的理解，并制定战略以减少其对健康和经济的影响。我们理所当然地认为，我们在英国吃的大部分食物都没有微生物病原体的风险，但食品标准局（FSA）估计，每年约有240万例微生物食源性疾病发生，成本超过90亿英镑。食品腐败浪费也会带来经济威胁，增加零售成本;高达25%的食品腐败是由于微生物的作用。我们的使命是通过改善食品安全减少人类食源性疾病，并减少因食品腐败造成的浪费。为了做到这一点，我们将在三个主题中解决关键的食品安全问题：1）食品中的微生物威胁是什么？2)与微生物威胁的生存和成功相关的因素是什么？3)我们如何利用这些信息来提高食品安全和减少食物浪费？在整个计划中，我们将专注于关键生物和对食品安全具有战略重要性的问题，我们将利用并进一步发展我们可证明的专业知识。这些是弯曲杆菌，沙门氏菌，李斯特菌，假单胞菌，抗菌素耐药性（AMR）和通过使用宏基因组测序识别新出现的微生物威胁。由于病原体和腐败菌等微生物威胁作为复杂的微生物群落存在于整个食物链中，因此我们不仅关注感兴趣的关键生物，还将研究可能支持其生存或持久存在的其他微生物。主题1，已建立和不断发展的食品系统中来自食品的微生物威胁，我们将确定哪些微生物威胁存在于我们的食物中-特别是较新的食物类型。我们的目标是通过研究食源性细菌种群内基因流动的遗传多样性和动力学，了解微生物威胁如何传播并导致疾病或食物腐败。特别是我们将评估与消费者偏好、贸易关系和气候变化相关的食品中不断变化的微生物威胁。在主题2中，微生物在既定和不断变化的食品系统中的生存，我们将定义与微生物威胁的生存和成功相关的因素。我们的目标是通过了解存在的细菌的生活方式来更好地了解微生物的生存和适应，例如生物膜，社区协会和/或无生长的代谢。为此，我们将使用我们的专业核心服务，包括信息学、测序和显微镜，对整个食物链中的样本以及人类临床样本进行研究。在主题3，降低食品安全威胁和应对紧急需求的灵活能力中，我们将使用前两个主题产生的数据来提高食品安全和减少食物浪费。我们将与QIB，学术界，政府和行业内的利益相关者合作，应用我们基础研究中获得的科学证据，以改善对未来风险的评估，并为控制食品安全和复原力的威胁提供信息。我们的能力将保持灵活性，以便我们能够根据需要迅速应对突发的国家需求，我们的工作方案旨在与我们的既定利益攸关方一起，通过提供科学知识和充当微生物食品安全知识和培训中心，改善安全和营养食品的生产，减少食品腐败损失。
