Looking at Table 1 provided by gophert, I thought at first that it was the answer to the age old question
"What have the Romans ever done for us?"
As for Ian Roger suggestion of licking the parcel clean,
I cannot help but think that the greatest danger with that activity would be the postal worker with a bad case of diarrhoea who had handled the package after failing to wash his hands correctly.
Of course, if after all this jocularity you are still worried about catching a dose of something nasty from the package,
you could always immerse it in boiling water for ten minutes to sterilise it.
