Mark Clasuon is a microbiologist at Western Kentucky University. He says: "The environmental swabs were collected using culturette systems."
Equipped with the culturettes, WBKO set out to test the cleanliness of several eateries in town.
The Scottsville Road McDonald's was the first place we tested. Their play area consists of a series of tunnels for children to climb in. We swiped two interior areas of the playground.
Next, we headed to Chick-Fil-A. The play area there is indoors. It consists of tunnels and a car kids can pretend to drive. There's also an activity area for toddlers.
From there, we went to Chuck E Cheese. Kids have video games and other hands-on activities where germs could spread.
Last we took samples from the carousel in the Greenwood Mall. Kids have the handle of the horses and the mane to hold on to. Thus potentially spreading germs.
All of the samples were then put on ice. After we completed the swabbing process we went back to the Biology lab at Western.
Clauson says: "The first thing you want to do is generally you want to roll the sample over a quarter of the plate."
The next step is dispersing those cells evenly.
Clauson says: "Streak first quadrant. Flame. Streak second quadrant. Flame. And I'm going to go on and streak the third okay. There's the first sample and that's basically what we're going to do on all of them."
Last, but not least, we put the samples in an incubator to sit for 48 hours.
We took two random samples from each of the areas we tested and we only tested for coliform bacteria. That kind of bacteria contains fecal matter that can make people sick. Tomorrow we'll have the results of all the restaurants play areas and hear from management. What we find out may surprise you.
