We cannot protect ourselves from all threats in this world. We are dependent upon God for our protection. But, we must do what we can to prevent disease from overcoming us. A healthy Bible based diet is an important part of remaining disease free. There are other considerations when it comes to infectious disease. We understand the importance of washing our hands. Here is something else that will help to impress upon our minds the need to practice good hygiene
Avian scavengers, such as American crows (Corvus brachyrhynchos), have potential to translocate infectious agents (prions) of transmissible spongiform encephalopathy (TSE) diseases including chronic wasting disease, scrapie, and bovine spongiform encephalopathy. We inoculated mice with fecal extracts obtained from 20 American crows that were force-fed material infected with RML-strain scrapie prions. These mice all evinced severe neurological dysfunction 196–231 d postinoculation ( = 198; 95% CI: 210–216) and tested positive for prion disease. Our results suggest a large proportion of crows that consume prion-positive tissue are capable of passing infectious prions in their feces ( = 1.0; 95% CI: 0.8–1.0). Therefore, this common, migratory North American scavenger could play a role in the geographic spread of TSE diseases.

We see here a very real threat to human health from Mad Cow Disease and other TSE diseases such as Scrapie, Chronic Wasting Disease, and CJD. Prions are not easily rendered incapable of transmitting disease. They are very infectious and appear to be long lasting. One high risk activity that comes to mind is the practice of collecting drinking water from the surface of roofs. This is a common practice in some countries. Once the bird droppings land on the roof, there is great danger to human health.
