Mycotoxins are secondary metabolites that moulds produce naturally. Due to their ubiquitous presence in foodstuffs and their potential risk for human health, prompt detection is important. In this review, we present and critically compare recent advances in mycotoxin analysis. Although most validated detection methods are chromatographic, alternative strategies based on biosensing principles are emerging. Biosensors and sensor arrays provide selective, sensitive and accurate measurements. The feasibility of miniaturizing them so that they are portable, their simplicity and easy data interpretation make them useful as screening biotools to ensure the correct assessment of mycotoxins in food and to reassure the consumer.
