Will food spoil in the time it takes to walk home from market?

It depends on several factors, including:

- The type of food: Some foods, such as raw meat and poultry, can spoil quickly, while others, such as fruits and vegetables, can last longer.

- The temperature outside: Food spoils faster in warm weather. If it's a hot day, it's best to keep food in a cooler or insulated bag to prevent spoilage.

- The distance from the market to your home: If you live close to the market, the food will likely be fine. However, if you have a long walk home, the food may start to spoil, especially if it's hot outside.

As a general rule of thumb, it's best to err on the side of caution and refrigerate or freeze perishable foods as soon as possible. If you're unsure whether or not a food has spoiled, it's best to throw it out.
