T. G. Lee Dairy controversies

Claims associated with yellow plastic milk containers

T. G. Lee was associated with yellow plastic milk containers promoted as helping preserve milk quality and protect minerals and vitamins from fluorescent lighting. The supporting evidence was criticized because the studies cited by marketers had compared fibreboard with translucent plastic and had not tested yellow plastic jugs. The issue concerns the broader marketing of the packaging format rather than a documented finding that T. G. Lee alone commissioned or authored the studies.
