Much of this will come down to improving our systems from farm to table. Culling systems that can remove real spoilage issues at the farm and packing house. Improved logistics to move product quickly and under the right conditions to the point of sale or processing. An understanding by consumers of what is actually bad versus not pretty but okay to eat. Planning by the consumer is another important control....that is, don't buy so much or make too much of something that you get to the spot when you have to decide if it is still good because of shelf-life. We answer so many questions from people who are worried about a chicken dish they made days ago or a jar of pickles that is two months past the shelf-life. The key is to manage what you have so you never get to that point.
Then there are some who insist that the issue is the shelf-life dates used by manufacturers. Correct, these dates are mainly based on quality, not safety. However, increasing the date could mean that you get a lower quality product. Did you ever taste a shelf-stable juice product in a plastic container past the shelf-life...it may be safe, but it tastes...well, it doesn't taste...no flavor.
