Is RFK junior right to say America allows more toxins than the EU?

There are many reasons to question the wisdom of Robert F. Kennedy junior, Donald Trump’s nominee for secretary of health. This is a man, after all, who drove around all day with the carcass of a bear cub before dumping it in Central Park in New York. He claims incorrectly that vaccines cause autism, and champions dubious claims about the health risks of 5G phones and the links between prozac and school shootings. So when Mr Kennedy claims that America has “one thousand ingredients in our food that are illegal in Europe”, sceptics can be excused for assuming that he is wrong. But is he?
