Shoalhaven City Council does not intend to stop using RoundUp, despite a 'complete review' of RoundUp spraying ordered in the Illawarra.
"We use it regularly," said Daniel Bishop, co-ordinator for parks at Shoalhaven City Council.
"Almost all research indicates that it is safe to use. It is rated as probably carcinogenic, but that is still very low when alcohol and fast food are known carcinogens.
"Council staff are trained, we all follow safety directions, and we don't consider we are exposing our staff to any particular risk - in fact it is safer than many other products we use everyday."
He said he did not believe RoundUp posed a risk to the community.
"Obviously if you're suffering with cancer you don't want to think it just happened to you, you want to pin it to something," he said.
"But at the moment, the evidence that we have doesn't say that.
"When people are concerned, I refer them to the government website, which provides easy to read resources, which link back to more dense scientific studies, which is what good science does.
"If people still have concerns after that it's generally because they think there's some kind of world-wide government conspiracy or cover up, and there isn't much I can do about that."
Mr Bishop said the council's position was that the use of RoundUp was lower-risk and lower-cost than alternative methods of weed control.
"We do it to minimise brush-cutting, because it's noisy and annoying for people, and poses a greater manual handling risk," he said.
"We do investigate alternative systems, but at the end of the day they're not as effective, or they are way more expensive, or they just aren't suitable - we don't know what the effects of long term use of them are yet."
He said he understood concerns in the Illawarra stemmed from aerial spraying, which he said Shoalhaven City Council does not do, and that Shoalhaven City Council avoids spraying RoundUp in parks and playgrounds, as a nod to "public sensitivities".
There are no plans to stop using it for weed management elsewhere.
"We could stop doing it tomorrow and have the grass growing up around edges, and it wouldn't hurt anybody, except people would complain it looks untidy," he said.
