CEN ISO/TS 17919:2013

Microbiology of the food chain - Polymerase chain reaction (PCR) for the detection of food-borne pathogens - Detection of botulinum type A, B, E and F neurotoxin-producing clostridia (ISO/TS 17919:2013)

ISO/TS 17919:2013 specifies a horizontal method for the molecular detection of clostridia carrying botulinum neurotoxin A, B, E, and F genes by a PCR method. This method detects the genes and not the toxins, therefore a positive result does not necessarily mean the presence of these toxins in the sample investigated. ISO/TS 17919:2013 is applicable to products for human consumption, animal feed, and environmental samples.
The PCR assays for detection of genetic sequences encoding specific toxin types are described in annexes.

Microbiologie de la chaîne alimentaire - Réaction de polymérisation en chaîne (PCR) pour la détection de micro-organismes pathogènes dans les aliments - Détection des clostridies productrices de neurotoxine botulique de type A, B, E et F (ISO/TS 17919:2013)

L'ISO/TS 17919:2013 spécifie une méthode horizontale de détection moléculaire des clostridies portant les gènes A, B, E et F de neurotoxine botulique par réaction de polymérisation en chaîne (PCR). Cette méthode détecte les gènes, et non les toxines. Par conséquent, un résultat positif n'est pas nécessairement synonyme de présence de ces toxines dans l'échantillon examiné. L'ISO/TS 17919:2013 s'applique aux produits destinés à être consommés par l'Homme, aux aliments pour animaux et aux échantillons environnementaux.
Les réactions de PCR de détection des séquences génétiques codant ces types particuliers de toxine sont décrites.

Ta tehnična specifikacija določa horizontalno metodo za molekularno ugotavljanje prisotnosti klostridijev, ki prenašajo botulinusne nevrotoksine genov A, B, E in F, z metodo polimerazne verižne reakcije (PCR). S to metodo se ugotavlja prisotnost genov in ne toksinov, zato pozitiven rezultat ne pomeni nujno prisotnosti teh toksinov v preiskovanem vzorcu. Ta tehnična specifikacija se uporablja za proizvode za prehrano ljudi, živalsko krmo in okoljske vzorce. Preskusi PCR za ugotavljanje prisotnosti genskih zaporedij specifičnih tipov toksinov so opisani v dodatkih B in C.

This Technical Specification (CEN/TS) was approved by CEN on 16 April 2013 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
