The needles, which are issued to addicts by the Alcohol and Drugs Service as part of its needle-exchange programme to help reduce the spread of blood-borne diseases such as HIV and hepatitis C, were reported to have been found on Wednesday.
Photographs of packages containing syringes were posted on the community Facebook page ‘Jersey Ask, Advise, Advertise’, warning people to be careful when in the park with small children and pets.
A spokeswoman from the States police said that the incident had not been reported to them. She said: ‘This isn’t the first time, and when we are called we will go and clean it up, or contact Parks and gardens who will also do that.’
Anthony Andrews, director of St Helier Public Services, said: ‘This is an extremely rare incident. We carry out checks on our parks from the early morning until the early evening every day.
‘Following the report of these unused needles being found we have put in place extra checks. We have also been in touch with the relevant agencies such as the honorary police and the Alcohol and Drugs Service so that they are aware of the incident.’
