Maybe it is just the source and the processing: Mycotoxins are toxic chemicals produced by molds — tiny fungi that are found in the environment. Molds and mycotoxins may occur in crops like grains and coffee beans . Tiny Amounts of Molds and Mycotoxins Are Found in Some Coffee Beans

Why are there mycotoxins in my coffee beans?
When your food spoils and forms green, furry spots… that’s because of molds. Some molds can grow in edible crops, like grains and coffee beans, and produce toxic chemicals called mycotoxins (1). These toxins can cause poisoning when we ingest too much of them.
Another fun fact about your beloved coffee 
Here are just three of the pesticides commonly used on coffee beans:
- Methyl Parathyion is one of the most vile pesticides ever created, and is toxic to a wide swath of all living things–including humans.
- Endosulfan is toxic to most animals and takes a very long time to break down in the soil.
- Chlorpyrifos has been banned for household use in the U.S. as it can cause birth defects.
All of the above, and more, can show up in your morning joe.
(what’s scary is the ‘and more’…hmm)
and countries that allow some chemicals is what another country wouldn’t so never sure ‘what is being’ used outside the USA and how much etc?
Coffee is losing ground here 
Our bodies might be screamin’ stop the coffee please?
