In a examine geared toward assessing the affect of washing poultry on kitchen contamination, researchers discovered that greater than 1 / 4 of examine contributors contaminated salad with uncooked poultry—together with many examine contributors who didn’t wash the poultry. The examine highlights the significance of hand-washing and cleansing and sanitizing the kitchen so as to cut back the chance of foodborne sickness when cooking at house.
Washing uncooked poultry shouldn’t be really useful, because of considerations about inadvertently contaminating different meals and surfaces—and growing the chance 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 habits may need on lowering contamination within the kitchen,” says Ellen Shumaker, corresponding creator of the examine and an extension affiliate at North Carolina State College. “We additionally needed to get a greater thought of how, if in any respect, washing poultry really led to elevated contamination within the kitchen.”
For the examine, researchers recruited 300 house cooks who stated they washed poultry earlier than cooking it. The researchers despatched meals security info to 142 of the examine contributors through electronic mail, outlining risk-reduction efforts—together with the advice to not wash uncooked poultry throughout meals preparation. The remaining 158 examine contributors didn’t obtain the training intervention.
All 300 examine contributors have been then invited to check kitchens outfitted with video cameras that filmed meal preparation. Individuals 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. Individuals have been then despatched again into the kitchen to cook dinner the hen thighs, put together the salad, and clear the kitchen as they might at house.
What the examine contributors did not know was that the hen thighs have been inoculated with a innocent pressure of micro organism, which the researchers would have the ability 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 examine 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 stunned 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 palms 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 turned contaminated by the uncooked hen, whereas there was comparatively little contamination of close by counters,” Shumaker says. “This was just a little stunning, because the typical knowledge had been that the chance 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 turning into contaminated, even when the hen wasn’t being washed.
“Washing the hen continues to be not a good suggestion, however this examine demonstrates the necessity to give attention to stopping contamination of sinks and emphasizing the significance of hand-washing and cleansing and sanitizing surfaces.”
