The study conducted showed that 64% of the reusable bags tested were contaminated with some level of bacteria and close to 30% had elevated bacterial counts higher than what’s considered safe for drinking water.
One key containment was the presence of faecal intestinal bacteria. All meat should be individually wrapped before being put in your shopping bag.
Don’t use your shopping bags for anything other than shopping for safety sake. Shopping bags are not multi-taskers.
One tip I can offer is reusing the bags for collecting recycling at your house. We use the bags for this and they hold up well week after week. Because the bags are only used for recycling they are not taken out again for marketing trips. The bags that are have to be cleaned after each trip.
