How Restaurants Prepare and Cook Chicken
This page shows the study purpose, method, results, conclusions, and recommendations in plain language for the EHS-Net project titled Frequency of Inadequate Chicken Cross Contamination Prevention and Cooking Practices in Restaurants.
The findings and recommendations from this project are also in fact sheet format [PDF - 245 KB].
Chicken is commonly linked with foodborne illness, with most of these illnesses coming from Salmonella and Campylobacter germs. Illness linked to chicken can come from cross contamination. This occurs when raw, contaminated chicken touches other foods or kitchen equipment. Illness can also come from cooked chicken not reaching a high enough temperature (165°F) to kill any germs that might be inside it.
We don’t know much about how restaurants prepare and cook chicken. If we learn more, we can improve how restaurants prepare and cook chicken and can lower the number of foodborne illness outbreaks.
The purpose of this study was to describe how chicken is prepared and cooked in restaurants.
For preparation, we focused on whether restaurants and food workers took steps to stop cross contamination. These steps include
- Washing, rinsing, and sanitizing equipment used with raw chicken.
- Wearing disposable gloves.
- Using separate cutting boards for raw chicken and other foods.
For cooking, we focused on whether
- Managers knew the right cooking temperature for chicken.
- Food workers used thermometers to check the temperatures of cooked chicken.
- Food workers checked thermometers for accuracy.
Study Findings in Brief
EHS-Net found that many restaurants do not follow the U.S. Food and Drug Administration’s (FDA’s) advice for preparing and cooking chicken.
We collected data in 448 restaurants. These restaurants were located in the 2008 EHS-Net sites and we chose them at random.
State or local environmental health specialists collected the data. In each restaurant, they talked to a manager.
Most managers said their restaurants had a cleaning policy about equipment and surfaces used when preparing raw chicken.
- Most of these policies included the three steps recommended by U.S. Food and Drug Administration (FDA): washing, rinsing, and sanitizing.
- About 1 in 10 managers said they wash and rinse equipment but do not sanitize it.
- About 1 in 3 managers said they wipe equipment with sanitizer but do not wash or rinse it first.
One in four managers said that their workers do not always use gloves while working with raw chicken.
Four in ten managers said that they do not always have cutting boards assigned for use only with raw meat.
Less than half of the kitchen managers we talked to
- Knew the temperature to which chicken should be cooked (165°F).
- Said that their food workers use a thermometer to tell when chicken is fully cooked.
In restaurants that use thermometers, about 1 in 3 managers said that their thermometers are checked for accuracy less than once a month.Top of Page
We found that many restaurants did not follow FDA’s advice when preparing and cooking chicken.
- Many restaurants did not take steps to stop cross contamination when preparing chicken.
- In many restaurants, managers did not know the right cooking temperature for chicken.
- Food workers in many restaurants did not use thermometers to check the temperature of cooked chicken.
Restaurant management and food safety programs should work to improve chicken preparation and cooking. Efforts should focus on creating training and prevention programs that focus on
- Lessening the chances for raw chicken to contaminate other food or equipment.
- Cook chicken to the temperature recommended by FDA (165°F).
- Cross contamination: spread of germs from one surface or food to another by contact.
- Disposable: designed to be used once and then thrown away.
- Environmental health specialists: public health workers who enforce health and safety standards related to food and other consumer products.
- Foodborne illness: an illness caused by germs in food.
- Foodborne illness outbreak: when two or more people have the same sickness after eating food from the same place.
- Salmonella and Campylobacter: germs that cause foodborne illness.
- Sanitize: process to clean and disinfect a surface that will come in contact with food; involves using heat and/or chemicals.
