According to the Food and Agriculture Organization of the United Nations, Johne's disease is one of the most serious diseases affecting the cattle industry.[139] Although it is found in cattle populations throughout the world, the United States appears to have the worst paratuberculosis problem on the planet.[122] In 1997, the USDA released a long-awaited report of the national prevalence of Johne's disease. Surveying over 2500 dairy producers,[190] they showed that between 20 and 40% of US dairy herds were infected, a figure that they concede is probably an underestimate.[190] Since milk from an entire herd is likely to be pooled together in tankers for transport to processing plants, all the milk from 20 to 40% of US dairies is likely to be contaminated.[85]

Just as Crohn's disease is increasing in the human population -- it may be no coincidence that the United States also has the world's highest incidence of Crohn's ever recorded[116] -- Johne's disease is spreading among dairy cattle.[19] Johne's disease is spread primarily by the fecal-oral route. One can imagine how a cow with intractable diarrhea can thoroughly contaminate her surroundings[133] and just a few bits of swallowed manure can potentially infect a calf.[133] Overtly infected animals, losing up to 300 lb of body weight in one week[106] can shed as many as ten hundred trillion bugs a day.[30] One can also imagine what intensive modern farming practices have done for the disease.[85] Grazing bigger and bigger numbers of cattle on smaller and smaller plots of land is one of the reasons this dreaded disease is such a growing threat.[81] And every time animals are transported between farms, new herds may be infected. If no changes are made, the dairy herd infection rate is expected to reach 100%.[115]
