The East Northport residents are facing multiple counts of petit larceny and tampering with a consumer product.
According to police, the couple tampered to receive packages of Jell-O for free.
Detectives do not believe the couple intended on hurting anyone.
Last week, detectives said someone was taking boxes of powdered Jell-O pudding mix and replacing the contents with what investigators say is aquarium sand.
They then returned the packages to get a refund.
The tampered boxes turned up in four stores in Suffolk and Nassau counties.
Investigators say surveillance video led them to the couple.
