I have seen that Texas and most other states have rules about testing your birds for Pullorum-Typhoid. Seems that it's a type of salmonella. But I haven't really found anything about where it comes from or how your birds get it. Once you have infected birds how hard is it to get a clean "bill" of health. How is this salmonella different from the regular salmonella that birds and reptiles already have? Not that reptiles have this type. Are the effects on human different? I don't have any birds now. I am just about to get into this "hobby" I have no plans now to take things to market but I might one day. BTW this is my 1st post here. Thanks for having me!
