In a research geared toward assessing the impression of washing poultry on kitchen contamination, researchers discovered that greater than 1 / 4 of research contributors contaminated salad with uncooked poultry—together with many research contributors who didn’t wash the poultry. The research highlights the significance of hand-washing and cleansing and sanitizing the kitchen to be able to scale back the danger of foodborne sickness when cooking at residence.
Washing uncooked poultry shouldn’t be beneficial, attributable to considerations about inadvertently contaminating different meals and surfaces—and growing the danger of foodborne sickness.
“We needed to know what impact an academic intervention would have on getting individuals to cease washing poultry earlier than cooking, and what impact any ensuing change in conduct may need on decreasing contamination within the kitchen,” says Ellen Shumaker, corresponding creator of the research and an extension affiliate at North Carolina State College. “We additionally needed to get a greater concept of how, if in any respect, washing poultry really led to elevated contamination within the kitchen.”
For the research, researchers recruited 300 residence cooks who mentioned they washed poultry earlier than cooking it. The researchers despatched meals security data to 142 of the research contributors by way of electronic mail, outlining risk-reduction efforts—together with the advice to not wash uncooked poultry throughout meals preparation. The remaining 158 research contributors didn’t obtain the training intervention.
All 300 research contributors have been then invited to check kitchens geared up with video cameras that filmed meal preparation. Contributors have been requested to cook dinner hen thighs and put together a salad. After making ready the hen thighs, however earlier than placing the hen within the oven, contributors have been known as out of the kitchen to conduct a brief interview. Contributors have been then despatched again into the kitchen to cook dinner the hen thighs, put together the salad, and clear the kitchen as they’d at residence.
What the research contributors did not know was that the hen thighs have been inoculated with a innocent pressure of micro organism, which the researchers would be capable to detect. This allowed researchers to swab surfaces within the kitchen to see whether or not any cross-contamination occurred through the meals preparation and cooking course of.
When research contributors left the kitchen to conduct the interview, researchers swabbed the kitchen to establish any potential contamination. This course of was repeated after every participant had accomplished cooking the meal and cleaned the kitchen. The ready salad was additionally examined for attainable contamination.
Ninety-three % of the contributors who acquired the intervention didn’t wash the hen, as in comparison with 39% of the contributors who didn’t obtain the intervention.
Nonetheless, the researchers have been shocked to see that individuals who did wash the hen and individuals who did not wash the hen had related ranges of contamination from the uncooked hen of their ready salads.
So what provides?
“We predict the salad contamination stems from individuals doing a poor job of washing their fingers after dealing with the uncooked hen, and/or doing a poor job of sanitizing the sink and surrounding surfaces earlier than rinsing or dealing with the salad,” Shumaker says.
“No matter whether or not individuals washed their hen, the kitchen sinks grew to become contaminated by the uncooked hen, whereas there was comparatively little contamination of close by counters,” Shumaker says. “This was just a little stunning, for the reason that typical knowledge had been that the danger related to washing hen was as a result of water would splash off of the hen and contaminate surrounding surfaces. As an alternative, the sink itself was changing into contaminated, even when the hen wasn’t being washed.
“Washing the hen remains to be not a good suggestion, however this research demonstrates the necessity to give attention to stopping contamination of sinks and emphasizing the significance of hand-washing and cleansing and sanitizing surfaces.”
