Sea slug found on Manukau Harbour beach
2 September 2010
People are warned to look out for toxic sea slugs on all beaches across the Auckland region, after a sea slug was found
on the shores of the Manukau Harbour.
One sea slug was collected from Cornwallis Beach this week, and is assumed to be toxic. The sea slug will be tested for
the presence of tetrodotoxin (TTX) - as found in sea slugs washed up on Auckland's North Shore beaches.
Auckland Regional Council (ARC) and Waitakere City Council staff searched the beach yesterday and found no evidence of
other sea slugs.
"There is no doubt these slugs are very toxic to dogs, and potentially toxic to humans as well," says ARC group manager
monitoring and research Grant Barnes.
"Children and pets should be very closely supervised on all Auckland beaches."
Mr Barnes says recent surveys continue to show Narrow Neck and Cheltenham beaches as sea slug "hot spots", with divers
finding high numbers immediately offshore. Lower numbers of slugs were also found on other parts of the coastline
throughout the North Shore and the Hauraki Gulf.
Research into the toxicity and distribution of the sea slugs continues. The ARC will continue coordinating the efforts
of the various agencies involved in the response.
Public health advice
Auckland Regional Public Health Service makes the following recommendations:
* Children and pets need to be supervised on all Auckland beaches, not just those bordering the Hauraki Gulf.
* Adults, children and pets should not eat anything found washed up on any beach.
* Parents need to be aware of where their children are swimming or playing, and what they are handling.
* Sea slugs on any beach must be avoided. If you find one, mark the spot, leave well alone, phone the city or district
council and ask for an environmental health officer, who will collect the slug safely.
