Shiga Toxin E.coli (STEC)

"Detect the ‘Big Six’ – and more - with our Shiga Toxin E.Coli proficiency testing scheme"

Most E.coli strains are harmless and can live in the human gut without any issues. However, Shiga toxin-producing E.coli (STEC) strains can cause serious illness, and therefore testing for them in foods that may be at risk of contamination is a common requirement around the world. 

The AXIO Proficiency Testing Shiga Toxin E.Coli Scheme (STEC) includes all of the most commonly tested STEC serovars tested internationally. Unlike some other Shiga toxin E.Coli proficiency testing providers, we provide real STEC strains for O26, O45, O103, O111, O121, and O145 - known as ‘the big six’ in the USA – as well as O157:H7. As the organisms are pathogens, testing for them is qualitative rather than quantitative, and seeks to identify their presence rather than enumerate their levels.

Participating in our Shiga toxin E.Coli proficiency testing scheme also enables laboratories performing microbiological analysis of meat, food, and dairy products to monitor their performance and compare it with that of their peers. Additionally, we aim to provide information to participants on technical issues and methodologies relating to these types of testing.
