Fluoride Alert researcher Chris Neurath uncovered the 2010 tax return for NSF, the National Sanitation Foundation, the non-profit chemical company trade association which falsely certifies fluoridation materials to be safe.
For a non-profit or tax-exempt corporation, NSF makes a lot of profit.
NSF takes in some $75 million per year and has net assets of $136 million and provides certification that materials are safe, including fluoridation materials. And it has a $20 million per year profit and lots of money in the bank.
