California health officials have issued a warning against drinking a second lot of raw milk due to the bird flu virus.

The outbreak hit California dairy farms in the late summer, and shortly thereafter, some dairy workers handling the raw milk began to fall ill with avian influenza themselves. Today in the state, more than 400 dairy farms are suffering outbreaks of avian influenza.

The circumstances and positive testing of a raw milk sample in California don't make sense, say experts. Something is amiss.
