I have a friend who, whenever he looks into my fridge or pantry, tut tuts the fact that I have not disposed of cans of diet soda dating from the late 90s. Those solid chicken tenders way in the back of the freezer? The hunk of equally hard filet mignon that has survived the ice age? All perfectly comestible. As are the frozen string beans, the pasta I cooked a few months ago and decided to save for a wintry day, and the samosas with ice crystals on them. My position is that unless the food smells, looks or is otherwise guilty of unfortunate behavior, I’ll thaw it and eat it.
• Every year, consumers in rich countries waste almost as much food (222 million tons) as the entire net food production of sub-Saharan Africa (230 million tons).
• Fruits and vegetables, plus roots and tubers have the highest wastage rates of any food.
• The amount of food lost or wasted every year is equivalent to more than half of the world's annual cereals crop (2.3 billion tons in 2009/2010).
