title: Microbiological evaluation of foodservice contact surfaces in Iowa assisted-living facilities.
abstract: A study of 40 assisted-living facilities in Iowa was conducted to assess the microbiological quality of food-contact surfaces (work tables/counters, cooking equipment such as mixing bowls, and cutting boards) and a surface that could cross-contaminate food (refrigerator or freezer handles) to determine the effectiveness of cleaning and sanitation. Standards were set for foodservice for aerobic plate count, Enterobacteriaceae, and Staphylococcus aureus . Two facilities met standards for all five surfaces for each of the three tests. Fewer facilities met the standard for aerobic plate count than for the other two tests, and nearly three fourths of the facilities failed to meet the aerobic plate count for cutting boards. Critically, cross-contamination from these surfaces could result in contamination of food; thus, attention needs to be given to training and supervision to ensure proper hand washing and appropriate cleaning and sanitation procedures to reduce or eliminate cross-contamination.
