@howyourhouseworks.au: Your plastic chopping board isn't the clean choice 🔪🦠 Every scratch on a plastic board is a knife cut that shaved microscopic bits of plastic into your food. One North Dakota State University study estimated about 15 to 79 million bits in one person's food a year. Germs hide in the scratches too: in University of Wisconsin tests, scratched plastic boards were hard to clean by hand and germs left on wet plastic overnight multiplied, while on wood, new or old, germs soaked into the grain and nearly all died. A dishwasher can clean off germs, but it can't stop the shedding. Bin the plastic board. Get a hardwood one, scrub it in hot soapy water (never the dishwasher, it ruins wood), and stand it up to dry. #choppingboard #kitchentips #microplastics #germs #howthingswork
