Domestic cleaning should include washing out reusable shopping bags, it has been claimed.
Many people are now using re-usable bags for grocery shopping in order to cut down on waste.
However, a new study has revealed that food kept in the bags can leave behind harmful bacteria, Fox19.com reports.
Dr Charles Gerba, a microbiologist with the University of Arizona and leader of the study, told the news provider: “We’re talking maybe millions of bacteria in some of the bags, it depends how people handle them and store them.
“Meat products leaking in your grocery bags, putting E coli or salmonella in the bag and then you use that same bag when you go shopping the next time for raw produce or you come in contact with organisms that can make you ill.”
The study revealed that less than three per cent of people washed their reusable bags, while may also used them for storing other items such as laundry, risking cross contamination.
Dr Gerba advised consumers to wash the bags following every use.
According to government figures, around 45 per cent of shoppers in the UK claim to have bought a reusable bag but only 12 per cent regularly use one.
