Area of Interest
A new hydroponic farm contacted STX Bioscience to learn about different solutions for powdered chemicals at critical control points.
Problem
Because the facility does not have many drains, the store owners were concerned, on the one hand, that microbes were building up in the standing water with disinfectant liquids, and, on the other hand, that they were not aware of the possibility that they were being treated with a disinfectant.
on the other, the amount of water they were using. In addition, because the facility does not have a clean space for hygienic zoning, they were concerned about cross-contamination from forklifts coming in and out of the farm.
Context
As the only disinfection measure, a liquid quaternary ammonium product is used on the farm in the footbaths located at the critical control points at the entrances. The environmental monitoring program swabs (PSMA) are performed frequently in order to detect, mainly, Salmonella y Listeria, The customer was looking to reduce water usage and was interested in trying a powdered product.
Results
Microbiological Analysis
Before applying Ultra Step, In addition, swabs were taken and aerobic plate count (APC) and Enterobacteriaceae data were recorded in the footbaths of the farm inlets, which contained only liquid quaternary ammonium. The use of this product was then discontinued and Ultra Step was applied as recommended above. The data below clearly illustrates that Ultra Step controlled APC and Enterobacteriaceae better during the day than liquid quaternary ammonium. After the application of Ultra Step, the grower farm managers observed a total reduction of APC on footwear and forklift wheels at a distance of 10 to 20 ft (3 to 6 m) from the footbaths.
