Hands should be washed before pricking out tomatoes, especially if other crops or tobacco has been handled. Adhering seed coats should not be pulled off the cotyledons, since any virus present is more likely to be on the seed coat than in the seedling. Change clothing or provide overalls if workers or visitors have been in other crops and wash hands before handling the crop. It is too alkaline to use for hand washing, but is ideal for tools, crop wires and other surfaces. TMV is unusual in that the coat protein of the virus reacts with proteins in skim milk, and hence skim milk can be used as an inactivator of the virus.
Skim milk is quite safe for hand washing.
