Potentially Hazardous Foods (PHFs): Potentially hazardous Foods (PHFs) are foods that require time and temperature control in order to prevent bacteria growth. The following are considered PHFs: Cooked or Raw Animal Products: Meat, fish, and poultry. Dairy products, including custard pies. Eggs (except for air-dried, hard boiled eggs with an intact shell)
In chemistry, pH (/ p iË Ë eÉª tÊ /) (potential of hydrogen) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions.
