Offenders will be required to have a blood test if their bodily fluid comes into contact with a police officer, under proposed new South Australian laws.
Police can be exposed to infectious diseases, such as hepatitis C or HIV, when arresting, restraining or detaining an offender, Premier Jay Weatherill said on Tuesday.
"These laws mean that if an officer is exposed to a risk of contracting these diseases, the offender will be required to undertake a blood test," he said.
"While officers are already blood tested in these situations, some diseases are not detectable for months.
"This means officers can be left waiting for a considerable amount of time, which can be stressful for them and their families."
The premier will outline the proposal at a Police Association conference on Tuesday.
In the past 12 months, there were 279 incidents where officers came into contact with blood, 118 incidents involving officers being spat on and two occasions where an officer suffered a needle stick injury.
