The shelf life generally relates to a drug's quality over a specified period of time, whereas the expiration date relates to both quality and safety of a medication at a specific point in time. The Code requires food to be safe up to, and including, the date marked. The “Shelf Life” of food is how long it may be stored (exist on a shelf) before the quality deteriorates. 100,000/g within the shelf life of many chilled foods. At high contamination levels, less time would be needed by SSOs to reach the minimum spoilage level, thus, shelf-life would have to be reduced. It must be noted that that model predictions are based on observations made in artificial growth media and available product studies. This is not an exact science, it just a helpful guide.
