Aberdeen was the scene of a typhoid epidemic 50 years ago when more than 500 people were infected during the summer months of 1964.
The city effectively closed down as health officials battled to contain the outbreak. The source was eventually traced to an imported tin of Argentinean corned beef.
Prof Hugh Pennington, a leading bacteriologist, says lessons learned remain valid for public health experts today.
