In food safety study, 25% of participants contaminated salad with raw chicken — ScienceDaily


In a analyze aimed at examining the impression of washing poultry on kitchen contamination, scientists located that additional than a quarter of review individuals contaminated salad with raw poultry — including a lot of research individuals who did not clean the poultry. The review highlights the value of hand-washing and cleansing and sanitizing the kitchen in purchase to cut down the risk of foodborne sickness when cooking at home.

Washing uncooked poultry is not encouraged, owing to issues about inadvertently contaminating other food items and surfaces — and raising the risk of foodborne sickness.

“We preferred to know what outcome an educational intervention would have on getting folks to quit washing poultry prior to cooking, and what result any resulting modify in actions may well have on minimizing contamination in the kitchen,” claims Ellen Shumaker, corresponding creator of the examine and an extension affiliate at North Carolina State College. “We also required to get a much better plan of how, if at all, washing poultry actually led to improved contamination in the kitchen area.”

For the analyze, scientists recruited 300 house cooks who stated they washed poultry right before cooking it. The scientists sent foods security data to 142 of the study participants by means of email, outlining threat-reduction endeavours — which includes the recommendation to not wash raw poultry in the course of meals planning. The remaining 158 analyze contributors did not acquire the education intervention.

All 300 study individuals were then invited to check kitchens outfitted with video cameras that filmed food preparing. Individuals were being asked to prepare dinner hen thighs and prepare a salad. After planning the rooster thighs, but ahead of putting the hen in the oven, participants had been termed out of the kitchen area to perform a quick interview. Participants ended up then sent back again into the kitchen area to prepare dinner the chicken thighs, get ready the salad, and clean the kitchen as they would at household.

What the review contributors failed to know was that the chicken thighs were inoculated with a harmless strain of germs, which the researchers would be in a position to detect. This allowed scientists to swab surfaces in the kitchen area to see no matter if any cross-contamination occurred during the food planning and cooking system.

When examine participants left the kitchen area to conduct the job interview, researchers swabbed the kitchen area to detect any prospective contamination. This approach was repeated right after each and every participant had concluded cooking the food and cleaned the kitchen. The prepared salad was also analyzed for attainable contamination.

Ninety-three % of the individuals who received the intervention did not clean the rooster, as as opposed to 39% of the members who did not get the intervention.

Even so, the researchers have been stunned to see that folks who did clean the rooster and persons who didn’t wash the rooster experienced comparable concentrations of contamination from the raw rooster in their organized salads.

So what provides?

“We believe the salad contamination stems from folks doing a weak position of washing their fingers following dealing with the raw hen, and/or executing a lousy position of sanitizing the sink and surrounding surfaces right before rinsing or managing the salad,” Shumaker says.

“Irrespective of irrespective of whether folks washed their rooster, the kitchen area sinks became contaminated by the uncooked hen, though there was reasonably small contamination of close by counters,” Shumaker suggests. “This was a little astonishing, considering that the standard wisdom had been that the possibility connected with washing rooster was since water would splash off of the chicken and contaminate encompassing surfaces. As an alternative, the sink alone was turning out to be contaminated, even when the chicken wasn’t getting washed.

“Washing the hen is even now not a superior idea, but this study demonstrates the need to aim on stopping contamination of sinks and emphasizing the worth of hand-washing and cleaning and sanitizing surfaces.”

The work was performed with aid from FSIS.
