Now I go beyond what the article states. I take biosecurity measures when around our chickens, not just in regards to salmonella, but also to avoid introducing avian flu or other pathogens to the flock. Similar to steps that I would take if I was visiting a commercial facility or a poultry farm.
Having chickens is a good thing if your able to do it, but people need to take care, learn what they are doing and realize that chickens should not be handled as you would a dog or cat.
My son loved his chickens! He was an animal lover in general, but he really liked the chickens. He had over 50 and they were all named. Some would ride with him in his truck even.
