Would you like my cynical opinion?
Americans have been taught to fear everything. And I mean EVERYTHING! This country thrives on spreading fear. We have been encouraged to fear every bacteria known to man, flour, sugar, eggs, meat, fat, cheese, salt, butter, mayonnaise, milk, fruit juice, coffee, tea, outdated canned goods, swallowing spiders in your sleep, running into Bigfoot and rabid bears while you're camping, guns, knives, dogs, snakes, bugs, identity theft, economic collapse, government corruption, global warming, cyber-terrorism, pollution, earthquakes, hurricanes, floods, droughts, spending your old age in poverty, getting Alzheimer's or dementia, death, what your neighbors think, what strangers think, home burglaries, car-jackings, rising prices, attacks by terrorists, EMPs, solar flares, fear of anyone who seems different from us.
IMHO, most of this fearmongering falls into one of two boxes: Control and/or Profit. And most control seems to lead to profit. Politicians create fear so you'll pay more taxes for them to 'solve' the problem. Religious leaders create a fear of death or hell so you'll give them money to prevent it. Business people assure you that you can't live without their products (purchase of which leads to their profiting from you). For others, it's pure psychological control because they're sociopaths.
Getting back to the eggs: washed eggs spoil faster than unwashed eggs, so you have to buy them more frequently. This falls into the Profit box. Laws to wash eggs and disinfect eggs come from politicians who are desperate to control people, so this probably falls into the Control box. So crack the egg, stir it up, and pour half into the Profit box and the rest into the Control box, and after a bit of time passes, both will start to stink.
