Raspberry Syrup
Not infested under normal circumstances. Need not be checked
Products with raspberries as an ingredient may be used, as long as there are not whole raspberry pieces inside.
Raspberry Products (commercially made): Jellies, Jams and Yogurt
All jellies have no infestation issues, since they do not use actual pieces of raspberry.
Jams, however, do use pieces of raspberry, and could have infestation issues. One should avoid them.
Yogurt with raspberries should be avoided.
