There are over 80 pesticides used in Australia that are banned in other countries.

This includes 17 pesticides that have the potential to cause cancer, 48 that are potential hormone disrupters, and 30 that are classified as either extremely dangerous or highly hazardous by the World Health Organisation. These pesticides are used on foods we consume every day- fruits, vegetables, grains and more. You can find the list of the 80 pesticides, their use and potential risk here.

In most countries a pesticide has to be proven safe before it can be used but in Australia the reverse is true.

it is not just pesticides. Farmers are known to use chemicals to make their product big and appealing. For instance 'Thompson's Seedless' grapes when left to its own devices produces green grapes that are quite small. Farmers use gibberellic acid, a plant growth regulator, to enlarge table grapes and reduce the size and amount of seeds. The grapevines are often treated as many as three times over the growing period and this hormone is usually present in the fruit at the point of sale.
