The state's environmental watchdog continues to ask people in western NSW to make contact if they have any unknown pesticides in their homes as it steps up efforts to warn people of unsafe mouse baits.
NSW Environment Protection Authority (EPA) staff visited Coonamble last week following reports from NSW Health of suspected illness in the area from mouse baits containing zinc phosphide, NSW EPA regulatory operations director Gary Whytcross said.
The EPA had an extremely positive response from the Coonamble community with more than 480 flyers about that particular mouse bait handed out to businesses and community members who expressed interest in the information, he said.
"The EPA is grateful that our advice to only use suitable mouse baits in domestic settings has been extensively shared by the media and within the Coonamble community, the central west and other areas of NSW," he said.
"The EPA's Environment Line has received several calls for information and we encourage community members to call 131 555 if they require further information on safe removal."
The EPA continues to ask people to contact the line if they have any unknown pesticides at their homes.
Mr Whytcross said visits to other towns would be considered if the EPA received reports of zinc phosphide issues.
Country and urban residents in the Orana region have both reported of an outbreak of mouse numbers since the end of last year.
CSIRO researcher Steve Henry said in January the high numbers of the rodents resulted from a really good season and if the conditions continued, they would "keep breeding through the summer".
