Mississippi resident here. The media loves to throw around big numbers like "75%" of poison control calls were from people taking horse dewormer. They didn't give any details of how many people that is, even though they love to post numbers for cases, deaths, etc when it comes to covid. Three out of four people could be 75%. Worth noting, most all of those who called in about their self-poisoning had very mild effects and only one went to the hospital where they also had mild effects. They are fine.
I'm using the horse paste. Its fine. Its just like any other medicine, take too much and you could overdose. Take too many Tylenols, Aspirins, or Ibuprofens........that'll be the last headache you ever have.
