In reference to the FDA or the ag people, whoever, sprouting is safe. It doesn't shock me that they would put out such a statement. I mean honestly, does anyone feel it's any safer to handle meat on your counter top? Of course not! You have to be smart about it. Seeds by their nature have the ability to not pass on nasty stuff...it's when they are grown in a nasty environment that the sprouts could harbor bad stuff and yea, the same goes with meat or anything else we eat.
We sprout sunflower seeds without the sand, this is to the original poster. No need to use sand, really. Ours will sprout in about four to five days. Every day you start a new one and you keep the rotation going.
I personally put mine in mason jars and use the wire mesh to rise them. Then each day I empty the contents into a suet feeder so that the chooks don't waste them and I put them just out of easy reach...hehe I know I'm mean, but it's fun to watch chooks jump and try to get all the sprouts.
