It's likely that seals from South America brought the virus to North America long before European colonization, carrying a TB strain which predates the European one. It's also likely that humans passed on this earlier strain to their cattle.

Best line from the WaPo article: "But humans can still catch good old-fashioned seal TB too."

Don't do this.
