I don't know about Starbucks, but the tuberculosis question is not as simple as it sounds.

For a start, sheep and goats, much like other ungulates are susceptible to various strains of TB, but perhaps a bit less to the worst of the cattle strains than cattle are. There are many strains of many species, all of them more pathogenic to some species than others, and most of them pathogenic to more than one.

The importance of badgers as reservoirs and vectors of bovine diseases has been argued for years. I refuse to get into the details of that discussion.Another question, assuming that badgers are indeed important vectors, there is the question of how relevant they are to sheep and goats. To what extent do their paths cross? Are the same routes for infection equally active between badgers and sheep, as compared to badgers and cattle?

It would be nice to get some authoritative, unbiased information on such questions.
