Les coffrets de test pour la sécurité alimentaire offrent une procédure simple, fiable et rapide pour détecter la présence de bactéries pathogènes spécifiques. Le dosage repose sur des réactions PCR en temps réel utilisant une nucléase marquée en 5' pour amplifier une séquence génomique unique dans l'organisme cible. La PCR est une méthode utilisée pour amplifier une séquence d'ADN spécifique qui est généralement amplifiée dans une réaction contenant une ADN polymérase thermostable, des nucléotides et des amorces complémentaires de la séquence cible. Lorsque cette solution est chauffée, la molécule d'ADN se dénature et se sépare en deux brins. À mesure que la solution refroidit, les amorces se fixent aux séquences cibles par annelage dans les brins d'ADN séparés, et la polymérase d'ADN synthétise un nouveau brin en étendant les amorces à l'aide de nucléotides, créant ainsi une copie de la séquence d'ADN (amplicons). Lorsqu'il est répété, ce cycle de dénaturation, de recuisson et d'extension augmente de façon exponentielle le nombre d'amplicons cibles. Dans la PCR en temps réel, les sondes fluorescentes spécifiques sont utilisées pour détecter l'ADN amplifié par hybridation avec les amplicons. Ces sondes sont liées à un fluorophore à une extrémité et à un suppresseur (quencher) qui supprime la fluorescence à une autre. Si la séquence cible est présente pendant la PCR, une amplification se produit et la sonde est dégradée, provoquant ainsi une augmentation de la fluorescence. La fluorescence est mesurée par un détecteur et le logiciel associé trace l'intensité de la fluorescence par rapport au nombre de cycles, permettant ainsi de déterminer la présence ou l'absence de l'organisme cible.

Les kits de sécurité alimentaire constituent une procédure simple, fiable et rapide pour détecter la présence d'espèces animales dans la viande et les produits à base de viande. Le dosage repose sur des réactions PCR en temps réel utilisant une nucléase marquée en 5' pour amplifier une séquence génomique unique dans l'organisme cible.
Conformément à la Directive de la commission européenne 2002/86/CE, les ingrédients alimentaires doivent être déclarés. Dans le cas de viande et de produits à base de viande, les espèces animales doivent être mentionnées sur l'étiquette. En outre, l'authenticité des espèces peut être extrêmement importante pour les consommateurs pour des raisons économiques, médicales, culturelles et religieuses. L'utilisation frauduleuse de viandes bon marché à la place d'espèces plus onéreuses, l'ajout de viande dans des produits (végétariens) non carnés et la présence d'allergènes dans les denrées alimentaires témoignent clairement de l'importance du problème (Ballin, 2010 ; Dooley et al., 2004).
Plusieurs méthodes sont basées sur l'identification de protéines au moyen de procédés électrophorétiques et/ou immunologiques. Cependant, ces méthodes n'offrent aucune fiabilité lorsqu'elles sont appliquées à des produits hautement transformés et chauffés en raison de la détérioration des protéines. L'ADN est plus stable que les protéines pendant le traitement et même s'il peut être fragmenté en plusieurs procédés, des méthodologies génétiques modernes telles que les techniques basées sur la PCR permettent toujours l'identification de l'ADN à partir de différentes espèces présentes dans un échantillon (Lockley & Bardsley, 2000). Les techniques de PCR en temps réel sont particulièrement adaptées à ces produits, car les petits fragments d'ADN peuvent toujours être amplifiés et identifiés avec une sensibilité et une spécificité élevées (Dooley et al., 2004).

Successful PCR applications depend on well purified DNA. In diagnostics and analytics of food and medical samples PCR and real-time PCR has many advantages over conventional methods. In all cases it is of importance to have well purified DNA for subsequent PCR, real-time PCR, hybridization or sequencing purposes. Purified DNA leads to higher sensitivity and also specificity of PCR based tests in difficult matrices. With QuickBlue Extraction and Purification Kit you always get high DNA yields and highly purified DNA. The kit uses paramagnetic nano-particles for purification. It can help to purify DNA from difficult matrices like food or even blood in soil for applications in forensic sciences. DNA in Seawater can also be purified. This method avoids extensive centrifugation steps and can thus be applied in environments where centrifuges are not usable. The kits includes proteinase K as a reagent for cell disruption, so that extraction and purification can be performed with the kit. DNA yield from 1 ml bacterial enrichment is 10 μg of Genomic DNA. The protocol can be adapted to automated magnetic bead separation instruments.
