You seem very in denial about a lot of this. Obviously 'weird preferences' do not really explain these issues (I note you completely ignored the case of heavy metals in drinking water, hard to explain as a 'consumer preference' for cheaper but unusable water.) So you've chosen to pretend that well documented things do not exist or are trivial.. Libertarian Germans often have to tie themselves in knots to pretend that all the elements of their high-trust society would exist without paternalistic government, when it's enough to compare their society to most others in the world to establish the opposite!
What country does Ritter Sport come from? Is it considered luxury chocolate in that country?
The huge differences between husbandry and meatpacking standards in the United States and Western Europe are extremely well known. Most US meat products are not allowed to be imported to the EU because of this. I'm surprised you need a 'source' for this widely known fact pattern (which in fact, you yourself mentioned in your comment above - pork in the US can not be eaten rare). What US meat is exported is generally a completely different standard than what's sold domestically.
The ready availability and aggressive marketing of opiate painkillers in the US continued for around twenty years, many of it based in 'pain clinics' whose only service was writing scripts for pills. Such clinics do not exist in Western Europe. The govt cracked down on these at a point where addiction was endemic in some regions. The problem was demonstrably not 'tiny in relative terms'.
