An Observational Study of Thermometer Use by Consumers When Preparing Ground Turkey Patties

Area of Science:

• Food Safety
• Behavioral Science
• Consumer Education

Background:

• Consumer thermometer use is crucial for ensuring food is cooked to safe internal temperatures.
• Effective interventions are needed to improve consumer food safety practices, including proper thermometer usage.

Purpose of the Study:

• To evaluate the effectiveness of a brief food safety video intervention on consumer thermometer use during meal preparation.

Main Methods:

• Randomized experimental design with direct observation of meal preparation in test kitchens.
• Participants were assigned to a treatment group (watched a USDA food safety video) or a control group.
• Observed participants cooking turkey burgers and preparing a salad, recording thermometer use and placement.

Main Results:

• Participants who viewed the video were twice as likely to use a thermometer (75% vs. 34%) compared to the control group.
• Thermometer users in the treatment group were also twice as likely to place the thermometer correctly (52% vs. 23%).
• Sixty-seven percent of participants exposed to the video reported a behavioral influence in their kitchen practices.

Conclusions:

• A short, well-timed video intervention significantly improves consumer food thermometer use and accuracy.
• The timing and framing of behavioral interventions are critical for success in promoting food safety.
• Further research should explore additional messaging for optimal thermometer use, such as proper insertion techniques.
