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.
Upon arrival, you should check your shipment of lobsters. If they are not moving, you should cook them within a few hours. Otherwise, if they are stored properly, they may be kept alive for an additional 24 hours before cooking. Keep in mind, though, the sooner you cook lobsters, the sweeter they will taste.
