So I wanted to get to the bottom of this - is there really bacteria living in our humble sink? I devised a quick experiment to figure this out:
Two different swab samples would be taken from the sink- one first thing in the morning (to see if any bacteria are there under normal conditions) and another after running hot water with dishwashing liquid and emptying the sink. A negative control was done to confirm aseptic technique. These swabs would then be plated on a few different agar plates.
The plates were inoculated and incubated for 24hrs. The results are shown below. Note the order of the agar are: Blood, Choc, MAC and CNA.
Swab 1 - four colonies
Swab 2 - two colonies
The results were interesting. There were four different colonies present on swab 1 - showing that some baddies grow in your sink overnight and will remain there unless the sink is cleaned. Good news though - sample 2 shows that dishwashing liquid and hot water effectively kill a lot of the bacteria present.
So, looking at these results, I'm still going to wash my dishes in the sink.
On a different topic, depending on which days you visited my blog, you probably noticed it changed appearance a few times. I was playing around with a few different designs and have settled for this one - I like it a lot.
Last night was youth and AllStar was a bit low in numbers - the lowest we have had so far. I had this strange experience during the praise - it felt as if we were just putting on a show for the kids, and it reminded me of something that's been on my heart a bit lately - we really need to be seeking God on behalf of these kids - because He is the one who changes lives. He is the one who can make them whole.

about the sink thing.. well did u try first doing the dishes in the sink with hot water n dishwashing liquid, then taking the swab sample? hmmmmmm. well maybe not after doing all the dishes, but at least half of it. oh, or do one before, during and after! to see how much bacteria is contained in the water u use to wash all the dishes.
ReplyDeleteabout ur last paragraph, i agree.. a lot of intercession on their behalf is very crucial. i was thinking we should all come together (empire) to pray for all star on a regular basis. or we could do a month of fasting and praying for both allstar n empire, faithfully committing to doing that.
you sound like you should be doing science instead of podiatry! :p I would have done the dishes but mum had already washed them by the time I got up =/ (I used the other sink instead).
ReplyDeleteBut the main point I wanted to demonstrate was the effectiveness of dishwashing liquid killing bacteria. To further support the point I should have done what you said ;)
vry nice Jason!!!
ReplyDeletei think ur a brilliant critical thinker!!!
