Yellow Kitchen Sponges Pose Health Risks
Yellow kitchen sponges, commonly used for cleaning dishes, can be very dirty.
They contain many chemicals and tiny plastic pieces that can make you sick.
The sponge is also made of a material that helps bacteria grow, and these bacteria can get on your dishes and into your food.
Eating this bacteria can cause problems like stomach issues and even heart disease.
Experts suggest using safer cleaning tools like cotton towels or bamboo scrapers instead of yellow sponges to stay healthy.
Yellow kitchen sponges contain up to 50 chemicals that can disrupt hormones and leave residues on dishes.
Sponges shed microplastic particles that can be ingested, increasing health risks like heart disease and dementia.
Made mostly of cellulose, sponges can harbour up to 54 billion bacteria per square centimetre, transferring to food and causing gut issues.
Experts recommend replacing yellow sponges with safer alternatives like cotton towels, natural loofahs, bamboo scrapers, or stainless steel pads.
A 2017 study found that used kitchen sponges can contain 362 different types of bacteria, with some areas having alarmingly high bacterial counts.
