This article feels like a nothing burger. Here is the opening sentence from the Wiki page about Ethoxyquin[1]:

    > Ethoxyquin (EMQ) is a quinoline-based antioxidant used as a food preservative in certain countries and originally to control scald on pears after harvest (under commercial names such as "Stop-Scald").

It is still approved in the United States to treat pears after their harvest to prevent "scald" (browning of the skin). Also, it looks hit or miss if US or EU/Europe allows it. We can go back and forth with a list of food-related chemicals that US allows but EU/Europe does not (and vice versa).
