For those playing the home version of the game, Japan LOWERS
rather than "raises" the maximum limit.  Clearly 0.0005ppm is
a much lower limit than 0.05ppm.

"0.0005ppm" would be 0.5 parts per BILLION.

To visualize just how tiny an impurity this would be, lets
walk outside to our imaginary Olympic-sized swimming pool
(50m x 25m x 2m) which would hold 660,253 gallons of water.

Now 660,253 US gallons equals a slightly over 2.5 billion ml,
so 0.5 parts per billion would be 1.25 ml (roughly 1/4 teaspoon)
of contaminant in the pool.

The "former limit" of 0.05ppm would be 100 times as much, 125 ml or
about 4 ounces of contaminant in the same Olympic-sized pool.

And Chloromycetin?  Another obscure antibiotic, of course.

(As an aside, legitimate Olympic-sized pools are very rare. The
last one I saw was at the Hotel Renaissance in Kuala Lumpur,
Malaysia, and the time constraints of business meant I never
got time to take a swim, one of many reasons I quit jetting
around and started keeping bees.)
