Shoppers who’ve switched to reusable bags could be risking their health, with ­health professionals warning they’re the perfect breeding places for illness-causing bugs.

Bacteria, such as such as E.coli, and yeast and mould in the bags may lead to contamination* of food.

Pest controllers also expect to be busy as cockroaches enjoy tiny crumbs of food and warm, damp conditions ­inside reusable bags.

Vincent Ho, of Western Sydney University’s School of Medicine, said there was a greater risk of illnesses from reusable bags than ­single-use plastic bags — ­especially if raw meat was mixed with other items.

“It’s important for people to be aware that there is a greater risk of catching a food-borne* illness, especially if there is mixing of raw foods with other ready-to-eat foods,” he said.

“Raw foods should be carried in a separate bag … but just the presence itself of raw meats does increase the contamination risk of a lot of these food-borne illnesses.”

While washing reusable bags “does eliminate* virtually* all the pathogens*”, Dr Ho said research suggested most shoppers forgot to do that.

US surveys found 97 per cent of shoppers did not wash the bags.

Sydney Reliance Pest Management owner Tommy Docos said he had dealt* with several cockroach infestations* from reusable cloth bags being stored in cupboards.

“All cockroach species like them, but the main species that I’ve seen within those bags when they’re stored in cupboards is German cockroaches, which are a smaller breed,” he said.

“We’re definitely expecting more jobs. If people are going to use those bags more often they’re going to be storing them in their homes which means there’s more chance of cockroaches going to those areas.”

ABC Pest Control director Warren Bailey said he had been called out several times to deal with cockroach infestations in bags from ALDI, which has never given out plastic bags since opening outlets in Australia.

A NSW Food Authority spokeswoman acknowledged reusable bags “can be a source of contamination” and urged shoppers to “make sure you regularly wash them”.

CLASSROOM ACTIVITIES
1. Write a letter
In light of this research, is it fair to say that reusable shopping bags should no longer be used and we continue to use single-use plastic bags?

Present your opinion in a letter to the editor of Kids News. Your letter should clearly outline your opinion and your reasons that support it. It should also acknowledge repercussions of this course of action. For example; if you believe we shouldn’t reuse bags, acknowledge how this may affect the environment. Or if you believe we should reuse bags, acknowledge what other steps we may need to take so we don’t make ourselves sick.

The following Kids News articles might provide some evidence or reasons that help support your opinion.
