Reusable bags might be eco-friendly, but experts say they could be putting your health at risk.
The UK’S Food Standards Agency (FSA) warns that using the same vessel to carry raw and ready-to-eat food and other household items can spread harmful bacteria and cause nasty stomach bugs.
According to the watchdog, deadly germs such as E coli and campylobacter can even be transferred from the outside of packaging when bags are reused.
“Ideally, you should have enough bags to carry raw foods, ready-to-eat foods and non-food items such as washing powder separately,” The FSA’s website states.
“Keep enough bags for life for raw foods only and don’t use the same bags again for ready-to-eat foods or for carrying other household items.”
It’s advised that reusable bags be colour-coded or labelled to avoid any mix-up.
