ISO 10273:2017 spécifie une méthode horizontale pour la recherche des Y. enterocolitica associées aux maladies chez l'homme. Ce document est applicable
-      aux produits destinés à l'alimentation humaine et animale, et
-      aux échantillons d'environnement pour la production et la distribution des aliments.

Mikrobiologija v prehranski verigi - Horizontalna metoda za ugotavljanje prisotnosti patogene bakterije Yersinia enterocolitica (ISO 10273:2017)

Ta evropski standard opisuje metodo za določanje mineralov in elementov v sledovih v živilih z uporabo optične emisijske spektrometrije z induktivno sklopljeno plazmo (ICP-OES) po razklopu pod tlakom.
Ta metoda je bila potrjena v medlaboratorijski študiji v skladu s standardom ISO 5725 [1] o otroški hrani, soji, siru, piščančjem mesu, pšenični moki, jabolčnem soku, jastogu in mleku s kalcijem v razponu 70–7178 mg/kg, z bakrom v razponu 0,60–16,40 mg/kg, z železom v razponu 0,88–77 mg/kg, s kalijem v razponu 605–14.312 mg/kg, z magnezijem v razponu 45–1174 mg/kg, z manganom v razponu 0,44–5,12 mg/kg, z natrijem v razponu 11–2220 mg/kg, s fosforjem v razponu 72–9708 mg/kg, z žveplom v razponu 26–8542 mg/kg in s cinkom v razponu 0,16–43,5 mg/kg.
