What's in a flavor

So I've been researching horse wormer online now for what's best. And of course, along with all of them working for their specified bugs, the flavor of those tiny tubes is ABSOLUTLY CRITICAL for its proper fucntion. At least that's what the advertising would have me believe. What I was wondering is who had that job to make sure that it actually tastes that way and like chemicals. Who apples for that job. 'Oh yeah, a job opening as a flavour taster eh? Boy oh boy! I'm all all over that job application!'

Bet that guy was in for a surprise. Any ways, the search continues
