Swabs arrive at the laboratory

Thanks to all our participants who swabbed their kitchens in our opening "kitchen safari" at the weekend. We picked up the samples on Monday morning and rushed them down to the microbiology lab, where Rich was ready to begin the processing. The first stage was to stabilise all the samples, so that the various bits of bacterial DNA on each swab wouldn't degrade any further. Every cotton bud was clipped and put into a small plastic tube, to which various chemicals were added. Then followed several rounds of mixing everything together and heating things up, before a final round of centrifuging completed the process. Everyones' samples are currently in the industrial-sized fridge, awaiting the next step which is scheduled for Wednesday.
