This law is not preventing airtight packaging in weights above 1.5kg and I bet that the store will still get these produce shipped in weights above that. So, what I understand what you are saying is that the hour or so of you picking it up at the shop until you put it in your fridge will result in "losing weeks of storage time", but I can't understand how that is possible. Can you explain?
Throwing a bunch of produce together in large masses is generally a very good way of getting it to rot. Having it shipped, individually wrapped bundles in moisture controlled plastic bags, inside of larger containers, now that works.
Yep. That's a good job picking out the most easily transported and stored produce. Of course you're failing to find photos of giant stacks of leafy greens for a reason.
