Food like meat, poultry, milk and cream should be kept out of the Danger Zone (between 4 and 60 °C (39 and 140 °F)). Anything between that range is considered dangerous and can cause pathogenic toxins to be emitted, resulting in severe illness in the consumer. Another way to keep food from

One of the age old techniques for food preservation, to avoid mold and fungus growth, is the process of drying out the food or dehydrating it. While

Issues of food spoilage do not necessarily have to do with the quality of the food, but more so with the safety of consuming said food. However, there are cases where food has been proven to contain toxic ingredients. 200 years ago,
