Flavr Savr tomato: The world's first genetically-engineered food

In 1994, biotech company Calgene brought the world's first genetically-modified food to supermarket shelves.

The Flavr Savr tomato kept fresh for 30 days and could be shipped long distances without going off.

Yet the world was wary of this new food, and it took 10 years and $100m of investment to get it to market.

In 2017, the firm's then-CEO Roger Salquist told Claire Bowes about his mission to revolutionise the world's food.
