Abstract:

In recent years, a large number of studies have shown that Helicobacter pylori may be a food-borne pathogen,
and milk is one of the most likely sources of its infection. Isolation and culture of H. pylori from food samples is exacting
and time-consuming. At present, PCR and related technologies, which have high sensitivity, are applied to detect trace
amounts of H. pylori in food samples such as milk. However, there is lack of rapid and effective detection methods and
related standards for H. pylori in food samples although a variety of specific and mature assays are currently available for
clinical use. This review focuses on recent progress in contamination and detection techniques of H. pylori in milk and dairy
products, so as to provide some references for further research on transmission and pathogenic mechanisms of H. pylori.

Key words: Helicobacter pylori, cow’s milk, dairy products, detection techniques
