Critical limits mark the minimum or maximum acceptable level of an identified food safety hazard at each critical control point (CCP). The 2 hour / 4 hour rule, for example, identifies the maximum acceptable amount of time that food can be in the Temperature Danger Zone (5°C – 60°C) before it must be thrown out.
The 2 Hour/ 4 Hour Rule tells you how long freshly potentially hazardous foods*, foods like cooked meat and foods containing meat, dairy products, prepared fruits and vegetables, cooked rice and pasta, and cooked or processed foods containing eggs, can be safely held at temperatures in the danger zone; that is between ...

Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours.
Two hours is the limit for keeping food safe outside the refrigerator or freezer; one hour if the outside temperature is 90 °F ( 32.2 °C) or above. Frozen food can thaw if it is exposed to the sun's rays even when the temperature is very cold.

The key is to never let your picnic food remain in the “Danger Zone” — between 40 °F and 140 °F — for more than 2 hours, or 1 hour if outdoor temperatures are above 90 °F. This is when bacteria in food can multiply rapidly, and lead to foodborne illness.
The 7 hour rule is a sales and marketing strategy introduced by Daniel Priestley in his book “Oversubscribed”. The core premise is that, it takes 7 hours of cumulative interaction time between a lead and a company to build the necessary trust, understanding and desire to want to buy your product or service.

Myth: When I microwave food, the microwaves kill the bacteria.
