Weekend reading: food animal markets and disease transmission
I thought this 2023 report was well worth a look.
Microbial diseases of animals can be transmitted to humans, and vice versa (witness COVID-19 in mink and zoo animals). Some of these have led to serious epidemics. Lots of people are worried that Confined Animal Feeding Operations could easily become the source of new and deadly forms of influenza.
But what interested me in this report is that industrial farm animal production is one of a great many sources of potential infectious disease transmission.
A few of the many examples, some well known to have caused Salmonella infections:
- Pets
- Hunted animals
- Production of bat guano and coyote urine (who knew?)
- Backyard chickens
- Crocodile farming
- Petting zoos
- Research animals
The report is cautious on the topic of the origin of COVID-19:
At the time of this writing, scientists continue to debate the precise origins of the virus but there is no question as to the impact it has had. Indeed, few aspects of daily life in the United States remain untouched.
The implication is clear. We need much better monitoring of animal markets for pathogens.
The United States has no comprehensive strategy in place to address the threat of zoonotic disease. There are serious regulatory deficiencies across almost every animal industry. Large information gaps exist, and disease can seep between these cracks.
Lots to learn here and think about here.
