My lawn is always greenest above the laterals from my septic tank. I was wondering if I were to plant a vegetable garden there if the gray and black water from the septic would render the vegetables inedible.
Thanks
There is a larger truth behind this, but I don’t know what it is.
Fertilizer in the form of herbivorous manure is OK (chickens, cattle, rabbits, etc.)
Fertilizer in the form of omni/carnivorous manure is bad.
I think it would be a really bad idea to do this. I found this on a pro-recycling poo site
Heh…I read the title of the OP. and I’m thinking that if you used the space between your pectorals, instead of directly on your lats…the dirt wouldn’t fall off when you laughed. 
I’m not up on the appropriate terms, so I’m not sure what a “lateral” is, but back in the day when we had a septic system, there was one area of the back yard where the grass always came up really lush and green. So I made it into a garden. We had *huge * crops of tomatoes and cucumbers. One year they grew faster than I could pick and can them. About half of them simply fell to the ground and rotted there. The following year, we had quite a number of volunteer plants that were quite good as well. No one had any particular bouts of illness that I can recall.
Now, bear in mind that we are not talking about direct fertilization by effluent or manure. Septic tanks are generally a ways down into the ground. What was fertilizing our veggies was whatever had filtered out of the tank and then up through the ground. Most of what goes into a septic tank, after all, is water. Think of the gallons of dishwater, hand-washing water, and so on. Even toilet flushes generally use gallons of water to dispose of a few ounces of urine.
Our well was uphill from the septic tank, by the way. We still have the well, but a few decades ago they made us put in sewers.
Other that the good advice above another reason to not plant anything on your drain field would be root damage to the conduit. The roots of some plants will damage the conduit and could result in some expensive drain field work. Corn is one of the worst, it will bore through concrete to reach water. I found this out from planting some in a concrete planter, it fell apart when I tried to remove the corn plant. It’s roots had cracked the planter from the inside out.
Plant bulbs. Shallow root systems, and you don’t eat them.
