Kitchen sponges: Replace weekly, says food safety officer

Food safety officer Ahana Nazar Hafis, based in Qatar, said kitchen sponges can harbor more pathogenic bacteria than a toilet seat due to their porous, damp nature trapping organic food debris.

Hafis warned that old sponges spread germs instead of removing them, as they stay wet and trap food particles, creating a perfect environment for bacteria growth.

She recommends rinsing thoroughly, squeezing out excess water, and letting sponges dry after each use, plus disinfecting regularly by soaking in hot water.

Despite cleaning measures, she advises replacing kitchen sponges weekly to prevent spreading germs while washing dishes.
