Thanks for bringing this topic up!
Bio security is something I am very familiar with having worked in a commercial dairy and around a pig breeding farm. Not to mention trips to commercial butchers. Having personally had Campylobacter Jejuni twice, there is more at risk than just animal health and considering I have other livestock on premises, cross contamination is something that will be prevented. Reducing random foot traffic is a big part of preventing cross contamination and introducing unwanted agents into the animal and people populations. Feed security and pest control are also issues to be addressed.
I also have other livestock on premises so, bio security and cross contamination are much bigger problems than just a public exposure issue.
At various points through college, I have worked a very broad range of farming and animal production activities though, the vast majority was centered around beef production, show cattle, and wheat. I should note that I earned my American Farmer degree from the FFA while an engineering student in college so, in addition to practical experience on a farm, dairy, and wheat field, I have a good solid academic background in agriculture which has been supplemented by a variety of extracurricular agricultural "adventures".
Compressed gases are a whole different set of challenges. I am a certified Hyperbaric Chamber Operator and a former EMT so, medical oxygen and compressed atmosphere is something I know a lot about. I have also worked with a lot of Liquid Nitrogen and various other specialized gases and liquids.
