The company routinely shuts down products that have become stale. Last year, it shut down Yahoo Directory, which was the cornerstone of the company when it first was founded in 1995. Over the past two and a half years, the company has discontinued more than 60 products.
The temperature range in which most bacteria grow is between 40 degrees F (5 degrees C) and 140 degrees F (60 degrees C). Raw and cooked foods should not be kept in this danger zone any longer than absolutely necessary.
Between one to two hours, according to the folks at StateFoodSafety.com. It takes roughly two hours for bacteria in foods to grow to dangerous levels, which is why you want to minimize the amount of time food is in the temperature danger zone (between 41 degrees and 135 degrees Fahrenheit). On days that are 90 degrees Fahrenheit or warmer, that time shrinks to one hour.
