HC Deb 10 June 1964 vol 696 c68W
59. Mr. Grimond

asked the Secretary of State for Scotland if there is any scientific evidence to show that typhoid bacteria can be present in a tin of corned beef for many years without contamination of the meat to an extent which would make it unpalatable.

Mr. Noble

I am advised that this is theoretically possible, but I am not aware of any scientific evidence which would determine the question.
