Weedkiller ingredient used in notorious cancer-causing Roundup is found in 80% of US urine samples

A commonly used weedkiller linked to cancer is appearing in more than 80% of urine samples from kids and adults in the U.S., according to a study.

'Glyphosate is the most widely used herbicide in the country, yet until now we had very little data on exposure,' Alexis Temkin, toxicologist at the Environmental Working Group, said in a statement. 'Children in the U.S. are regularly exposed to this cancer-causing weedkiller through the food they eat virtually every day.'

A survey of glyphosate - which is a widely used herbicide in the agricultural, garden, and home sectors in the country - was conducted by the Centers for Disease Control and Prevention program.

The survey found glyphosate in 1,885 of 2,310 urine samples from participants that supposedly represented the U.S. population. Participants aged between six to 18 made up a third of the samples.

Temkin cited the CDC study while also acknowledging that glyphosate is an active chemical in the weedkiller, Bayer's Roundup.
