Reusable shopping bags ‘pose food safety risk’

Reusable food shopping bags and packages can contain a high level of bacteria, yeast, mould and coliform counts which pose a significant food safety risk, according to a new study from Sporometrics, an environmental microbiology lab based in Canada.

Swab tests of reusable bags last November revealed a bacteria count of 1,800 colony-forming units, while 550 were discovered in Tupperware containers.“The test findings clearly support concerns that reusable grocery bags can become an active microbial habitat and a breeding ground for bacteria, yeast, mould and coliforms, concludes the study, which was funded by the Environment and Plastic Industry Council.“This is supported by the high bacterial counts showing that the bag interior can harbour or breed substantial bacterial populations.
