A giant blueberry weighing 20.4 grams has been declared the biggest in the world by Guinness World Records this week. The title was previously held by a berry weighing 16.2 grams

Farmers in Australia were left “stoked” when they noticed that among the blueberries they picked, there was one as big as a golf ball and weighing significantly more than average.

The giant blueberry, which is 39.31mm wide and weighs 20.4 grams - much more than the average of between 1 gram and 3.5 grams - was picked at a farm in Corindi, New South Wales, in November last year. On Tuesday, Guinness World Records publicly declared it the biggest blueberry in the world - a title previously held by a 16.2 grams berry with a diameter of 36.33mm grown in Western Australia.
