What you say is true in the literal sense Paul.
But in Food safety the term Ambient is generally used for foods which do not have to be stored in the refridgerator or freezer (Low risk foods) and can be safely stored at room temperature. Room temperature (also referred to as ambient temperature) is a common term to denote a certain temperature within enclosed space at which human beings are accustomed. Room temperature is thus often indicated by general human comfort, with the common range of 18°C (64°F) to 23°C (73°F).
If anyone knows of any establishments which require a HACCP based food safety management system putting in place I will be happy to give a quote to do this or indeed to train their staff to implement and monitor the said system... (Advertising for me OK)
