The ice cream had been bought at a grocery store in Trois-Rivières, Quebec, the Daily Mail reported.
The family had to go to a hospital for HIV tests as well as for Hepatitis A, B and C. They will also need blood tests for the next six months.
Christofferson has complained to the ice cream maker and is considering taking legal action.
The ice cream company Coaticook has said it will be conducting an internal investigation into what happened and stresses that this is the first time they have received such a complaint.
'We have so many internal controls here and in food production in general that having something like that show up in a food item, it's not normal,' said Jean Provencher, the owner of Coaticook.
Inspectors from the Canadian Food Inspection Agency are now looking into how the slip-up happened at the factory itself.
