Pressure treated wood is fine for a raised bed if you are going to plant ornamentals. If the bed will be used for planting vegetables, I'd either line the wood with plastic before filling with soil or I'd use cedar or redwood instead. The newer processes of pressure treating are safer than the old process, but the jury is still out on whether or not harmful chemicals can leach from the wood. So I'd err on the side of safety and line any pressure treated wood for a raised vegetable garden.
