What tragedy allegedly spurred Al Capone to lobby for milk date stamps?

Answer

A family member becoming seriously ill from contaminated milk.

The popular narrative surrounding Al Capone's alleged involvement in food dating suggests a highly personal catalyst. According to this legend, a family member, possibly a niece, reportedly fell gravely ill after consuming milk that had been adulterated, which was a common practice at the time involving masking spoilage with substances like chalk or formaldehyde. This supposed tragedy is cited as the motivation that drove the powerful gangster to take aggressive action, allegedly lobbying the Chicago City Council to mandate visible date stamps on all milk containers to protect public health, particularly that of children and pregnant women.
