Arizona Study Examines the Impact of Disinfectant Wipes on the Risk of Campylobacter Jejuni Infection during Raw Chicken Preparation

A study by researchers from the University of Arizona Mel and Enid Zuckerman College of Public Health and the Department of Soil, Water and Environmental Science found the use of disinfectant wipes after the preparation of raw chicken meat reduces the risk of Campylobacter jejuni infections. The study was published in the Journal of Applied Microbiology.

The researchers conducted a quantitative microbial risk assessment and forecasted the exposure to Campylobacter jejuni contaminated surfaces during preparation of chicken fillets and how using a disinfectant-wipe intervention to clean a contaminated work area decreases the risk of infection following the preparation of raw chicken fillet in a domestic kitchen.

Using a Monte Carlo simulation of the risk of transferring Camp. jejuni strain A3249, from various surfaces to hands and subsequently transferring it to the mouth was forecasted. The use of a disinfectant-wipe intervention to disinfect contaminated surface area was also assessed. Several assumptions were used as input parameters in the classical Beta-Poisson model to determine the risk of infection. The disinfectant-wipe intervention reduced the risk of Camp. jejuni infection by 2-3 orders on all fomites.

This risk assessment shows that the use of disinfectant wipes to decontaminate surface areas after chicken preparation reduces the annual risk of Camp. jejuni infections up to 99·2 percent, reducing the risk from 2 : 10 to 2 : 1000.
