According to the report, kitchen environments host more microbes than toilets, “ chiefly ascribable to the contribution of kitchen sponges, which were proven to represent the biggest reservoir of active bacteria in the whole house. ” More than toilets ?

The New York Times reported that while microwaving may kill the watery bacteria, “ the strongest, smelliest, and potentially infective bacteria will survive. ” But Michaeleen Doucleff—whose research while earning a doctoral degree in chemistry included growing, studying, and killing bacteria—wasn ’ metric ton convinced. Doucleff wrote for NPR that the mooch bacteria to be most implicated about—the food-borne pathogens—are “ weaklings ” that once heated even precisely a small moment, “ literally pop. ” ad

even the authors of the sponge study themselves said, “ sanitation by boiling or microwave treatment has been shown to significantly reduce the bacterial load of kitchen sponges and can therefore be regarded as a reasonable hygiene measure. ” But they then said, in the adjacent conviction : “ however, our data showed that regularly sanitized sponges ( as indicated by their users ) did not contain less bacteria than uncleaned ones. ” Huh ? Upon taking a deep honkytonk into the original leech study, food microbiologist Jennifer Quinlan told NPR “ there was no gain explanation of what ‘ regular scavenge ’ meant ” and that “ the study stated that the sponges were either microwaved or put in hot, saponaceous water. ” The latter method acting, Quinlan said, “ could actually encourage the bacteria. ” ( Did we mention the survey looked at only five sponges that people reported “ cleaning regularly ” in Germany ? ) Enter the U.S. Department of Agriculture. According to the USDA, both microwave and dishwashing sponges kills 99.9 % of bacteria. ( The sponges tested had been soaked in none other than prime beef juice. Yuck. ) indeed, who ’ s right ? While microwaving your sponges is not a failsafe, longterm solution, it can decidedly zap a good count of harmful bacteria and increase the life of your sponge. so, basically ?
