The 5-sec­ond rule

Australian Women’s Weekly NZ - - WELLBEING -

You may want to think twice be­fore us­ing the five-sec­ond rule for food that’s fallen on the floor. A re­cent study in the United States showed it takes less than a sec­ond for dropped food to be­come con­tam­i­nated by bac­te­ria. The de­gree of con­tam­i­na­tion var­ied for dif­fer­ent foods and sur­faces, with high-mois­ture foods such as wa­ter­melon pick­ing up the most bugs, and car­pet hav­ing the low­est trans­fer rate.
