Household, hospital wipes effectively removed peanut allergen

Common household and hospital cleaning wipes were effective in removing peanut allergen on typical objects found in hospital waiting rooms and cafeterias, according to study results.

Researchers in Canada smeared 5 mL peanut butter on a 12 inch by 12 inch square on a laminate table surface, a plastic doll and a textured plastic ball and 2.5 mL on smooth and textured book covers. After air drying for 5 minutes, the items were cleaned with a household wipe and two commercial hospital wipes. The researchers conducted a baseline test before the application of peanut butter and there was no detectable peanut allergen Ara h 1 on any item. After using the wipes, there was no detectable allergen on any of the items.

“It is reassuring that simple but thorough cleaning of toys, books and surfaces of many items that could be found in a hospital using common household or hospital cleaning wipes will remove the peanut allergen Ara h 1,” the researchers wrote.

The researchers, however, acknowledged there were limitations to their study. Porous items such as wood, cloth or loosely woven material were not tested. “These items may be more difficult to clean as peanut may penetrate the surface,” the researchers wrote.
