1.6 million birds killed in the last couple weeks due to bird flu just about 20 miles from me. Egg production site. 148000 turkeys as well in this area in the same time. I heard that they wouldn't allow the feed trucks going to other sites to drive past it to keep from possibly contaminating the trucks. Warmer weather all vehicles enter a wash bay that sprays all external parts of it, and if you leave your door open in the summer UPS drivers can be disinfected as well. I know. Winter they spray only the tires. With all the migrating waterfowl you end up with more cases this time of year, but infection rates are supposed to lower because of the cooler weather.
