The amount of time a potentially hazardous food is held within the temperature danger zone should kept as short as possible.
Potentially hazardous foods should be kept at safe temperatures to prevent bacterial growth. In general, perishable items should not be left out at room temperature for more than 2 hours; if the temperature is above 90°F (32°C), this time reduces to 1 hour. Once cooked or prepared, these foods should be refrigerated promptly and consumed within 3 to 4 days. It's essential to follow proper food safety guidelines to minimize the risk of foodborne illness.
Potentially hazardous food must be kept at safe temperatures to prevent bacterial growth. The danger zone for these foods is between 41°F (5°C) and 135°F (57°C). To ensure safety, foods should be stored below 41°F or above 135°F. Keeping foods within these temperature ranges helps reduce the risk of foodborne illnesses.

The US Food Code recommends that potentially hazardous food be cooled from 140°F to 70°F within 2 hours, then further chilled to 40°F within another 4 hours. So after 2 hours, the food should either be reheated to 165°F or placed in the fridge to cool further.
It is important to be cautious of potentially hazardous ready-to-eat foods because they can contain harmful bacteria that can cause foodborne illnesses if not handled properly. To ensure safe food handling, ready-to-eat foods should be stored at the correct temperature, kept separate from raw foods, and consumed before their expiration date. It is also important to wash hands before handling these foods and to follow proper hygiene practices to prevent contamination.
Actual time to spoilage is uncertain, but potentially hazardous food should not be unrefrigerated for more than 2 hours. Less time is better. The food should be cooled from 140°F to 70°F within 2 hours, then chilled down to 40°F within another 4 hours. Either quick chill the food with an ice bath or separate it into smaller containers to facilitate faster cooling.
To control the growth of any bacteria that my be present, it is important to maintain the internal temperature of food at 135F or above or 41F or below. Potentially hazardous foods (PHF) or time/temperature controlled for safety foods should be heated or cooled quickly so that they are within the temperature danger zone as briefly as possible.
Potentially hazardous food should not be left unrefrigerated for more than two hours. Less time is better, especially if the ambient temperature is around 90°F - then reduce that to one hour. Then it should either be reheated or refrigerated.
Plain cooked pasta should be treated as any other potentially hazardous food. It should be refrigerated within 2 hours or within 1 hours if the ambient temperature is around 90°F. Less time is better.
Under existing laws, States do not have broad authority to control how hazardous materials are stored, used, transported, and disposed of within their borders
If you ship hazardous materials from, to, within or through the territory of the United States you must comply with the DOT regulations governing transportation of hazardous materials.
