A practitioner took a scab from someone with a mild case, made an incision in the skin of a healthy person, and infected that person with the scab. Sheep-scab is a loathsome skin disease due to an acarian parasite.
I did find this link, but I don't think it will help out much, because there is nothing on the internet about it, other than this. http://en.allexperts.com/q/Wild-Animals-705/frozen-crab-life-thawed.htm. Or you can go to this link. Its about frozen lobsters coming back to life after thawed.
The best way to keep the lobster fresh for a recipe the next day or until the day that you intend to use is to keep them alive until use. In other words, you will not be allowing them to die by submerging them into the fresh water and kill them, but will rather a quick technique that will send them to coma and still keep them alive for being fresh.
