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.
Buy frozen lobster that has never been thawed. Check that it was blanched before freezer storage and stored at extremely low temperatures, around 0 degrees Fahrenheit (-18 degrees Celsius). Sometimes you wonât want to cook the lobster immediately. Store the frozen lobster in an airtight freezer bag. If vacuum-sealed, it can be stored in a freezer for up to one year. Of course, you can also purchase lobster that is not frozen. Cooking a live lobster involves a different process in some ways, though.
