for me , a farmed animal would be considered WC, not saying they all are , but in most cases these farms are used to smugle wild life. They have no real control measures to prevent it.
here's an interesting read, this one is about GTPs but it will give you an idea why it's next to impossible to tell between WC and FB, this is why a farmed animal should always be considered WC. even if it is a real farmed animal, chances are almost 100% certain that it was in contact with WC ones.
