Foodwise is a website dedicated to reducing how much food is thrown away.
It does have the slightly ambiguous statement of “Australians throw out $7.8 billion worth of food every year”. I know it felt like I spend billions on food, but I think it means all together.
One page in particular has some great tips on how to reduce wastage in regards to temperature: http://www.foodwise.com.au/get-foodwise/refrigerating-food.aspx
Within the hospitality industry there are reasonably strict guidelines on the storage and transport of refrigerated items which focus on providing safe food for customers. The other benefit, however, is that food is kept fresher and lasts longer.
So follow the advice at the site and you will benefit from food that lasts longer, but should also be safer to eat.
