The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C).
While most guidelines state two hours, a few indicate four hours is still safe. T: Temperature Foodborne pathogens grow best in temperatures between 41 and 135 °F (5 and 57 °C), a range referred to as the temperature danger zone (TDZ). They thrive in temperatures that are between 70 and 104 °F (21 and 40 °C). [3] O: Oxygen
Most bacteria can survive near freezing temperatures, but cannot absorb nutrients, grow or replicate; however, L. monocytogenes has the ability to grow at temperatures as low as 0 °C which permits exponential multiplication in refrigerated foods.
Some pathogens that contaminate food are even showing up in the U.S. for the first time thanks to climate change. Threat of foodborne pathogens is growing with climate change, experts warn Skip to ...
Infectious diseases that are sensitive to climate can be grouped into: vector-borne diseases (transmitted via mosquitos, ticks etc.), waterborne diseases (transmitted via viruses or bacteria through water), and food-borne diseases.(spread through pathogens via food) [4]: 1107 Climate change affects the distribution of these diseases due to the ...
Psychrotrophic bacteria and fungi are able to grow at refrigeration temperatures, and can be responsible for food spoilage and as foodborne pathogens such as Yersinia. They provide an estimation of the product's shelf life, but also they can be found in soils, [25] in surface and deep sea waters, [26] in Antarctic ecosystems, [27] and in foods ...

From 2017 to 2019, the report found, around 40% of foodborne illness outbreaks with known causes were at least partly associated with food contamination by a sick or infectious worker.
