Foodstuffs - Detection of irradiated food containing bone - Method by ESR spectroscopy

This draft European Standard specifies a method for the detection of meat containing bone and fish containing bone which have been treated with ionizing radiation, by analysing the electron spin resonance (ESR) spectrum or electron paramagnetic resonance (EPR) spectrum of the bones. On the basis of results of analysis of meat containing bone from duck, frog, goose, chicken, hare, lamb, turkey, beef and pork, it is assumed that the same signals occur when other animal species are analysed.

Lebensmittel - Nachweis von bestrahlten knochen- bzw. grätenhaltigen Lebensmitteln - Verfahren mittels ESR-Spektroskopie

Dieser europäische Norm-Entwurf legt ein Verfahren zur Identifizierung von mit ionisierender Strahlung behandeltem knochenhaltigem Fleisch und grätenhaltigem Fisch fest. In diesem Verfahren wird das ESR- (Elektrospinresonanz) oder EPR- (Elektronen Paramagnetische Resonanz) Spektrum des Knochens bzw. der Gräte analysiert. Auf der Grundlage der Ergebnisse von Untersuchungen an Knochen von Ente, Frosch, Gans, Huhn, Hase, Lamm, Pute, Rind und Schwein kann angenommen werden, daß dieselben Signale auftreten, wenn andere Tierarten analysiert werden.

Produits alimentaires - Détection d'aliments ionisés contenant des os ou des aretes - Méthode par spectroscopie RPE

Ce projet de norme européenne définit une méthode permettant la détection des viandes contenant des os et des poissons contenant des arêtes qui ont été traités par rayonnement ionisants, par analyse du spectre de Résonance Paramagnétique Electronique (RPE) ou de Résonance Electronique de Spin (RES) des os et arêtes. Sur la base des résultats des analyses effectuées sur des os de viande de canard, grenouille, oie, poulet, lapin, agneau, dinde, boeuf et de porc, il est possible de conclure que les mêmes signaux sont présents lors de l'analyse de n'importe quelle autre espèce animale.

Overview

EN 1786:1996 (CEN) defines a laboratory method for the detection of irradiated food containing bone by using electron spin resonance (ESR), also called electron paramagnetic resonance (EPR) spectroscopy. The standard covers analysis of bones from meat and fish to determine whether the product has been treated with ionizing radiation. Tests performed on species such as duck, frog, goose, chicken, hare, lamb, turkey, beef and pork indicate similar ESR/EPR signals are expected for other animal species.

Key topics and requirements

• Scope of application: Detection of ionizing radiation treatment in meat and fish products that contain bone.
• Analytical technique: Use of ESR/EPR spectroscopy to measure radiation-induced free-radical signals in bone mineral and organic matrix.
• Sample selection: Bones separated from food matrices (meat or fish) are the analytical target; the standard addresses a range of common species and assumes transferability to others.
• Measurement and interpretation: Comparison of ESR spectra against non-irradiated reference signals to identify characteristic radiation-induced peaks. The method emphasizes controlled measurement conditions and documented interpretation criteria.
• Quality control: Requirements for using appropriate controls, reproducible instrument settings and validated procedures to ensure reliable identification of irradiated material.
• Standard adoption: Published by CEN and adopted by national bodies (for example SIST EN 1786 in Slovenia), ensuring harmonized use across laboratories.

Applications

• Food inspection and regulatory compliance: Routine screening of meat and fish consignments to verify whether irradiation treatments were applied.
• Border and import control: Detection of non-declared irradiated products entering markets with labelling or treatment restrictions.
• Food industry quality assurance: Manufacturers and processors can apply the method to monitor ingredient sourcing and supply chain compliance.
• Research and accreditation laboratories: Validation studies, method development and proficiency testing for ESR-based detection of irradiated food.

Who should use this standard

• Government food control laboratories and regulatory authorities
• Accredited testing laboratories performing food safety analyses
• Food producers, processors and quality assurance teams
• Research institutions working on food irradiation detection methods

Related standards

• Standards on food irradiation labelling, general food testing methods and laboratory quality management complement EN 1786 where regulatory, procedural or accreditation context is required.
