Wow, safety first! That's a lot to think about, especially when all of this is supposed to be fun as a hobby or business; like anything else there are dangers to look out for. like anything else, darn it! I also saw a YouTube video of someone getting a strange skin infection called Mycobacterium marinum that may have been mentioned here in another place in the forum. I thought it should be mentioned here, but should not take away from your TB warning. Thank you!Mycobacterium marinumMycobacterium marinum
