Wesley Goodridge, a Grade 7 student from Ontario, has won a gold medal and a $10,000 university scholarship at the 2026 Canada-Wide Science Fair for a project investigating whether science can help people determine if milk is actually spoiled.
His project, Test Before You Toss, explores the use of adenosine triphosphate (ATP) as an indicator of microbial activity in milk, potentially offering consumers another way to judge freshness beyond best-before dates and traditional smell or taste checks. His research looks at whether science can help consumers determine if milk is still fresh instead of relying only on a best-before date or their senses.
