What Happens to Food Left in a Car Overnight?

Leaving food in a car overnight, especially at temperatures around 30 degrees Fahrenheit, can be a serious food safety hazard. This is because perishable foods, like meat, poultry, dairy, and eggs, are susceptible to bacterial growth when exposed to warm temperatures.

The “temperature danger zone” for perishable foods is between 40°F (4°C) and 140°F (60°C). When perishable foods are in this temperature range for more than two hours, bacteria can multiply rapidly and cause spoilage. Even at temperatures as low as 30 degrees Fahrenheit, bacterial growth can occur, albeit at a slower rate.

Why is a Car a Bad Place to Store Food Overnight?

Vehicles parked outdoors can experience extreme temperature fluctuations, especially during overnight hours. Even in mild weather, the temperature inside a car can drop significantly at night, creating an ideal environment for bacterial growth.

What are the Risks of Eating Food Left in a Car Overnight?

Consuming food that has been left in the temperature danger zone for extended periods can lead to foodborne illnesses such as salmonella, E. coli, and staphylococcus aureus. These illnesses can cause symptoms ranging from vomiting and diarrhea to more severe complications.

How to Avoid Food Safety Risks When Leaving Food in a Car

To avoid food safety risks, follow these precautions:

• Refrigerate promptly: Leftovers should be refrigerated within two hours of cooking.
• Discard perishable foods: If leftovers have been left unrefrigerated at temperatures above 40°F (4°C) for more than two hours, they should be discarded.
• Use coolers: When transporting food for extended periods, use insulated coolers with ice or cold packs to maintain a safe temperature.
• Reheat thoroughly: If leftovers have been left in a safe temperature range, they should be reheated to an internal temperature of at least 165°F (74°C) before consuming.

Additional Tips

• Avoid leaving perishable foods in a hot car, even for short periods.
• If leftovers must be left in a car overnight, try to park in a shaded area or open the windows slightly to allow for air circulation.
• Monitor the temperature inside the car regularly using a thermometer.
• If in doubt about the safety of leftovers, it’s always best to err on the side of caution and discard them.
