Checking for Cleaning via Luminometer

Interesting data from University of Guelph research team on the connection between luminometer readings and laboratory bacteria culture results are found in this report:
"Validation of commercial luminometry swabs for total bacteria and coliform counts in colostrum-feeding equipment." (Journal of Dairy Science, 100:9459-9465 October 2017).

Using the test equipment available to the general public (Hygiena luminometer and various test swabs) they conclude that the Aqua-Snap Total and Microshap Coliform swabs are an acceptable alternative to traditional bacteria counts to evaluate cleanliness of colostrum-feeding equipment. About 59% of their surfaces has bacteria counts of at least 100,000cfu/ml - so they had plenty of dirty surfaces to check.

Note that they used rinse samples (15ml sterile water rinsed the surfaces to be tested).

At our vet clinic we use the Ultra-Snap testing swaps (direct collection from dry surfaces with moistened swabs). The data below are from a commercial dairy June 2016-July2017. Note the up and down pattern at certain sample sites. Acceptable ATP values were selected by the dairy.
