Well, I’m glad that’s settled:
Biology students at Aston University in the UK monitored how quickly E.coli and common bacteria spread from surfaces to food such as toast (butter side down, no doubt), pasta and sticky sweets — with time being a significant factor in the transfer of germs.
Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time according to the findings.
The type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from laminate or tiled surfaces to moist foods making contact for more than five-seconds.
“We have found evidence that transfer from indoor flooring surfaces is incredibly poor with carpet actually posing the lowest risk of bacterial transfer onto dropped food,” said Professor Anthony Hilton who headed the study.
It’s better not to drop food at all but if you’re going to drop it the faster you pick it up the safer it is. I’m glad that’s settled. It will be very reassuring to my wife.
I now look forward to a definitive answer on whether the jelly side lands down a majority of the time.
