Crypto Isn’t Seasonal. It’s Constant.

For years, many in the industry assumed Cryptosporidiosis was a seasonal problem — peaking in winter stress or during spring calving.

But the data tells a different story.

Crypto is endemic, meaning it’s always present. By six weeks of age, nearly all calves have been exposed. The real driver isn’t the calendar — it’s the environment.

In fact, some of the highest pressure occurs during hot-weather months, particularly in large calf-raising regions like California, Idaho, and Texas. High density, shared environments, and constant calf flow create ideal conditions for ongoing exposure.

And unlike some pathogens that fade with the seasons, Crypto doesn’t go away.
