bring a friend to hold your groceries in the car and look for signs of contamination in your food.

Explanation:

The blog excerpt specifically mentions using a thermal bag or cooler to keep perishable foods at the proper temperature when groceries need to be kept in the car for one to two hours. This is a direct solution provided in the text. Placing food in plastic sandwich bags in the front seat doesn't address temperature control (which is key to preventing bacterial growth as per the science section - bacteria multiply when perishables are unrefrigerated for too long). Bringing a friend to hold groceries and look for contamination signs also doesn't solve the temperature - related food safety issue.

Answer:

Use a thermal bag or cooler to keep perishable foods at the proper temperature while transporting.
