dc.description.abstract The extensive use of pesticides to protect agricultural crops necessitates reliable tools for the detection of residues in food and water, thus ensuring environmental protection and consumer safety. Neuroinhibitors such as organophosphates and carbamates are widely used in agriculture because of their high insecticidal activity and their rapid mineralisation in the environment. Since they do not only inhibit insect acetylcholinesterase (AChE) but also interfere with neural transmission in other organism, including humans, they represent a potential hazard for human health and environmental food chains, and thus require continuous assessment. Recent reports on organophosphate contamination in baby food have initiated the reassessment of permitted residual concentrations of these compounds in view of the US Food Quality Protection Act. Here we present a rapid detection method for neurotoxins in food, which can increase the number of tested foodstuff and thus improve the consumer safety. We developed a highly sensitive and rapid food analysis biosensor based on disposable screen-printed thickfilm electrodes. Matrix problems were solved by using isooctane as extraction solvent. The performance of this amperometric test was checked by three different food matrixes, namely orange juice, apple and peach baby food. The detection limit was comparable to chemical standard methods and met the requirements for monitoring the maximum residue levels in baby food set by the EU. en
