Huffpost reporter Alexandra Emanuelli said that her outsourcing is increasingly being delivered to the door in a less delicious state, but because she had been waiting for more than an hour, she had to succumb and eat the cold food dry.

If the sauna is delivered, it is not only not delicious, but may be dangerous. Food scientist Bryan Quoc Le said that when food is placed at or near the room temperature, contaminated microorganisms will reproduce rapidly; although the speed depends on the degree of sterilization, sugar, moisture and acidity of the food, most of the food will have spores or bacteria on the surface of the food.

Emarenli said that many people have experienced the experience of putting the vegetables they bought in a hot car or leaving the leftovers in the kitchen for hours; according to data from the U.S. Department of Agriculture, most foods are put at room temperature for about two hours to cause a threat to health.

Food scientist Tiffany Swan said that since the out-of-sale food that you don't know how long it takes to be placed at the appropriate temperature, it should be eaten as soon as possible, or put it in the refrigerator immediately, and heat it to 165 degrees Celsius (about 73 degrees Celsius) before consumption.

Ellen Schumaker, a food safety expert at North Carolina State University, said that if the weather is too hot (like the recent hot dome and the highest temperature frequency breakdown), two hours may be shortened to an hour. She said that when the outdoor temperature is 90 degrees Celsius (about 32 degrees Celsius) or above, the food can only be left for about an hour before refrigeration to prevent bacteria from growing.

Be careful "dangerous area"

"dangerous area" refers to the "sweet pot" in which microorganisms begin to grow, usually between 90 and 140 degrees Celsius (about 32 to 60 degrees Celsius). According to Lebanon, when food is cold or heated to these temperatures, it will cause microorganisms to reproduce 100 to 1,000 times in large quantities within hours.

Lei said that if meat, dairy products, seafood and poultry are already in "risk areas", be careful because it is very likely to breed pathogens. He reminded that the source of food poisoning does not necessarily change color or smell, so smelling is not enough to determine whether food is safe.

The temperature is not right when the foreign sales are delivered, so what should I do?

Although you should not waste food, if you eat it, you will get sick. It is best to throw it away. Swan said she believes in her stomach. If the food sounds, looks problematic, or looks a little unfavorable, and not just "not hot", then don't risk it and throw it away immediately. In this case, it is likely that this dish was not made with the latest ingredients and took too much time during preparation and delivery.

Shumeik pointed out that an appeal can be filed with the food delivery platform, or contact the restaurant and explain the situation; each state has different regulations on delivery of food sold.
