Food safety affects everyone worldwide and will remain a global challenge to human health in the foreseeable future requiring the rapid, sensitive, efficient and inexpensive detection of food contaminants. Biosensors have long been investigated to be part of a solution. In fact, current research trends of nanoscale science and technology, efforts of miniaturization and connectivity enabled through the internet of things boost biosensors’ capabilities to a degree that they surely will play a major part of the answer to this global challenge. Surprisingly though, the adaption of such biosensors to function along the entire food value chain and hence also include important aspects of sustainable agriculture and food fraud has been neglected so far. In this review, the latest developments of biosensors addressing these issues are presented for the years 2015–2019 and point toward important new strategies needed to truly ensure safe food in a sustainable global market.

食品安全影响着全世界的每个人，并且在可预见的未来将仍然是对人类健康的全球挑战，需要对食品污染物进行快速，灵敏，高效和廉价的检测。长期以来，一直将生物传感器作为解决方案的一部分进行研究。实际上，当前纳米技术的研究趋势，通过物联网实现的小型化和连接性的努力将生物传感器的功能提高到一定程度，以确保它们必将在应对这一全球挑战中发挥重要作用。但是，令人惊讶的是，迄今为止，这种生物传感器在整个食品价值链中的功能适应性也因此而缺乏，包括可持续农业和食品欺诈的重要方面。在这篇评论中
