Infection Control Program Deficiencies in Legionella Monitoring and Environmental Disinfection
Summary
The facility failed to maintain an infection prevention and control program for its Legionella Water Management Program (WMP). The March 2026 WMP identified control measures for the facility’s seven cottage sets and main building, including chlorine testing, water heater temperatures, and restrictions on decorative fountains, but it did not specify how the control measures for the four occupied cottages and main building were to be monitored, the frequency of monitoring, acceptable ranges, or what actions would be taken when control measures were outside acceptable ranges. The facility policy titled Legionella Water Management Program, revised March 2026, stated the WMP would include specific control measures, acceptable ranges, a system to monitor control limits and effectiveness, and a plan for when control measures were not being met or were not effective. During interview, the Maintenance Supervisor stated the facility was monitoring chlorine and pH for all cottages and the main building, but did not have acceptable ranges or parameters and was only writing down the levels. The supervisor also stated they were unsure what actions would be needed if the control measures were outside acceptable ranges. During observation, the chlorine level tested from a sink in the main building lower basement office was 0.11 milligrams per milliliter, and the supervisor was unsure whether that level was within acceptable range. The Infection Preventionist and Superintendent also stated the WMP lacked specifics on monitoring frequency, acceptable ranges, and actions to take when control measures were not within acceptable parameters. The facility also failed to ensure staff used an EPA-registered disinfectant for cleaning and disinfecting environmental surfaces and resident rooms. The cleaning and disinfecting policy stated environmental surfaces in resident cottages, including walls and floors, would be properly cleaned and disinfected with an EPA-registered disinfectant, and manufacturer instructions would be followed. During observation, custodial staff reported using Waxie 330 odor controller/degreaser on resident room surfaces, Waxie 210 neutral floor cleaner on floors throughout the facility, and Waxie 730 hydrogen peroxide disinfectant for some kitchen, dining, family, and high-touch surfaces. Record review showed Waxie 330 was not a registered disinfectant and Waxie 210 was a daily floor cleaner, not a registered disinfectant. Staff also stated Waxie 210 was used on all floors, including in a resident TBP room, and the Infection Preventionist stated the facility process was to use Waxie 730 to disinfect resident rooms, floors, and high-touch surfaces, while Waxie 210 was not the correct process for resident room disinfection.
