No, not just anyone. Serum is a controlled substance, an experimental drug, because it is manufactured in another country.
The FDA stance has implemented standards because of this, which has made it difficult for just anyone to buy.
The keeper must locate a doctor who is willing to submit his curricula vitae and participate in the program. This is difficult, and this is why so many hobbyists haven't entertained the idea of stocking their own serum. Problems arise as their are accidents, and institutions stocking the life saving serum are called forth as moral obligation. Further problems arise as they are left footing all expenses for the serum. In turn, problems arise for the private keeper as these institutions can't reason logically why there shouldn't be restrictive legislation prohibiting the private keeper from keeping venomous.
Many have become very angry with Jim Harrison, who supports private keeping, but if you had lost as much money as he has, there comes a time when you must do what is best for yourself. The man milks venomous snakes for a living, and he is at greatest risk of snakebite. He is sick of our hobby taking and stiffing him on his serum.
