Glyphosate Exposure in Horses
At present there is no research on glyphosate exposures specifically for equines. Views on its effects on horses are mostly theory based on observation and studies done on humans, cattle, mice, and chickens.
Glyphosate has been getting a lot of attention for its connection to cancer, but that’s far from the only health concern related to the weed killer. There is a long and growing list of dangers, but one of the biggest ones that doesn’t get a lot of attention is the fact that it’s an endocrine disruptor.
In fact, the glyphosate-based herbicide Roundup can cause damage to the endocrine system at levels that are legally permitted in drinking water. This is according to a study carried out in Australia by researchers at Flinders University. They found that Roundup killed the cells that produce progesterone in women, causing their progesterone levels to drop.
