Though perhaps you don't know it, what you're actually saying is, "don't spread it immediately. Let it decompose for a year or more."
Septic tanks are something akin to a composting pile. You put the crap in and bacteria decomposes it. After the bacteria deals with the liquid, the liquid spreads into the septic field (underground). The solids go to the bottom of the tank where bacteria deal with them as well.
Nonetheless, I would NEVER spread wet, sloppy septic gunk directly onto the ground. The wet environment means that there could be unwanted pathogens still existing in the matter. Spreading directly is inviting the pathogens that you're body expelled (think an intestinal affliction, or the flu) back into the open where small hands can pick it up and bring it back into a body. If it's going directly into the ground, make sure that area is fenced off for quite some time. In my opinion, spreading directly is just bad practice.
In larger quantities our waste IS biohazardous waste.
