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.
Lobsters should be chilled and live. Blanch at 212Â° for 60 seconds in a 2% salt brine (1.5 ounces, or roughly 1/2 cup, of non-iodized salt or sea salt to 2 quarts of water). Chill after blanching in cold running water or in a tub with a mixture of 50% water to 50% ice.
