New Zealand OKs sodium nitrite bait
The New Zealand Environmental Protection Authority (EPA) has approved an application from pest control company Connovation (Auckland) to import and manufacture encapsulated sodium nitrite (ESN) for use in a bait to control possums and wild pigs. ESN is considered to be less hazardous and toxic and more humane than many similar substances used for animal control, the EPA notes. It quickly breaks down in the body, so there is less risk of other animals being poisoned from eating the carcasses of possums or pigs that have consumed the bait. An antidote is available that is suitable for humans and non-target animals, the EPA adds.
