Cows in Cache Valley have been dying unexpectedly from what appears to be a natural sickness.

Multiple farmers have said they woke up Friday morning to find that their cows had died without warning. Deaths have been reported in Smithfield, Providence and along the west side of the valley.

While the cause is still unknown. It is possible that babesiosis is to blame. Babesiosis — or Redwater — disease is carried by blood parasites and can cause a rapid progression of illness and death.

Amanda King, supervisor over the department of agriculture, said she could not confirm that it is the cause, but she is leaning in favor of that explanation. She said the cause should be known later Friday afternoon when a specialist comes in.

While the milk from the dead cows will probably not be sold, King warns against drinking milk from sick cows.
