It’s a Weird World

Five-sec­ond rule is too gen­er­ous for fallen food NEW BRUNSWICK — It might be time to re­con­sider the five-sec­ond rule when think­ing about eat­ing food that has fallen on the floor.

Re­searchers at Rut­gers Univer­sity in New Jer­sey say in a new study that bac­te­ria can con­tam­i­nate food that falls on the floor in­stan­ta­neously.

The find­ings were pub­lished this month in the Amer­i­can So­ci­ety for Mi­cro­bi­ol­ogy’s jour­nal.

Re­searcher Don­ald Schaffner said the five-sec­ond rule is a “sig­nif­i­cant over­sim­pli­fi­ca­tion of what ac­tu­ally hap­pens when bac­te­ria trans­fer from a sur­face to food.”

Schaffner’s re­search isn’t the first to con­clude that the fa­vorite ex­cuse for why that yummy snack that fell on the ground is still OK to eat is wrong.

The re­search did find that longer con­tact time means more bac­te­rial trans­fer, but that the type of food and sur­face is just as, or more, im­por­tant.

The Rut­gers re­searchers tested wa­ter­melon, bread, bread and but­ter, and gummy candy on stain­less steel, ce­ramic tile, wood and car­pet.

They found that wa­ter­melon had the most con­tam­i­na­tion, and that trans­fer of bac­te­ria is af­fected most by mois­ture.
