2+. If viral RNA is detected in pasteurized milk, it means that milk was not identified through current procedures and is going on to be pasteurized for commercial use. This suggests either asymptomatic shedding from cows or inadequately disinfected milk processing equipment.
3. If cows are infected and shedding virus while showing no detectable clinical signs of infection, then the epidemic (technically epizootic) may be much broader than previously thought. This is, IMO, very bad news that makes surveillance and ultimately containment much harder.
4. I do agree the milk supply is safe to consume. Viral RNA is not infectious for influenza & it persists after heat inactivation at pasteurization temperatures. There's no reason to think pasteurization doesn't magically work for H5N1 only when it does for other viruses.
5+. I'm not attributing this to malice, incompetence, territorialism, bureaucracy, or anything else, but it's very clear that this apparent lack of transparency and urgency to share these relevant data are greatly harming both the US and global capacity to respond.
We know that if you don't want an outbreak to become an epidemic or a pandemic, it needs to be contained quickly. This news further shows that it has neither been contained and there is no evident rush to do so. This is both alarming and profoundly depressing.
Many have correctly commented about the loss of trust in public health that this is furthering, but the problem goes beyond that. Here the agencies leading this response have forfeited leveraging the full capacity of the international scientific community to respond.
Pandemics are global events by definition. The US—the country where I am from, was trained, still work extensively in, and once claimed leadership in pandemic preparedness—is not the only country impacted. It's a matter of time before we find infected cows elsewhere.
Cattle—both dairy and beef production—is big business around the world. There are billions of cows. Failing to share information rapidly not only hurts food security, the economy, and human/animal health in the US, it's preventing a global response to a major global threat.
I am frequently asked to comment on "lessons learned" from SARS-CoV-2. Now I have yet another example of a critical lesson that has decidedly not been learned: if there's an emerging pandemic threat, you leverage all your resources to respond as fast and effectively as possible.
The lack of data and information sharing occurring here is disgraceful and inexcusable. The global scientific community is eager to leverage what we've learned from the last pandemic—at devastating cost to us all—to prevent another one. The government needs to help, not hinder.
