This blog is going to be a little different then most, but
hopefully it still meets the requirements for an A! Well, the first part of
this blog is going to be a follow up on my “Remember the 5-Second Rule?” blog.
I found an article that answered a question that was left on that specific
blog. So, hopefully the commentator reads this blog too!

A group of biology students led by a microbiology professor,
Anthony Hilton, studied the amount of E.
Coli and Staphylococcus aureus bacteria
on different substances after they had been dropped on the floor for three to
30 seconds. The researchers used toast, pasta, biscuits and sticky, sweet foods
according to the author of this article, Jenn Harris. Like the previous blog I
wrote, the researchers also dropped the food on different surfaces such as
carpet, tiled, and laminate. Like the previous article I “blogged” about, the
researchers found bacteria from floor to food was lowest when dropped on
carpet. Now here’s where the commentator’s question gets answered. “Bacteria
was most likely transferred from laminate or tiled surfaces to moist foods that
were dropped for more than five seconds.” The author did a great job of
explaining the main point of this article and made the results easy to
understand. No questions from my perspective were needed because of the
author’s great job in writing the main points of the article. Once again, do
you use the 5-Second Rule?
Now since the blog was a follow up I wanted to do, I had
already searched for different microbe and microbiome articles to write about,
but I found this video to interesting not to share. Maybe next week I’ll
“blog” about it, but see for yourself! Would you like these "gadgets"?

I have always wondered about the five second rule and if it really did work or if it just wasn’t true. But now I know the truth behind this mystery. I myself have eaten food off of the floor when I drop it, and I never really thought about all the microbes that could have been picked up by the food. Now since I have been in this class I am always paranoid about microbes, especially microbes on our food. What really surprised my though was the fact that foods dropped on carpet had less bacteria than foods dropped on tile or laminate, I would have thought that carpet had more bacteria on it than the tile or laminate floors. Another thing I found really interesting was the that amount of bacteria transferred to the food was about the same regardless of time, which means that no matter how fast you pick up your food it’s going to have bacteria on it. Now that I have read this blog I’m never going to eat food that I have dropped.
ReplyDeleteI wrote about the 5-second-rule awhile back and was intrigued that it wasn't a myth. I thought it was really interesting that bacteria from carpeted surfaces were transferred to food less quickly as bacteria on laminated surfaces. This video you posted was really cool. I love how they present these tags, and I really hope it becomes a popular item. What I like the most is how they came up with it, and how it detects temperature and works with microbes. You should definitely do this as your next blog and dive into what these tags really are and how they work!
ReplyDeleteVery interesting! Amazing how it only takes seconds for microbes to transfer from one surface to another. It doesn't surprise me that carpet has the least amount of microbes, but I wonder if it has anything to do with it being dry? I wonder if it were a moist or humid carpet, if it were to have more microbes? It's also great to know that the 5-second rule isn't a myth. I know that I follow the 5-second rule.(but only in my house) Besides Dr. Diana said it helps improve our immune system.
ReplyDeleteThere's a great Non-Sequitur cartoon about the 5 second rule from the microbe's point of view. Take a look:
