If you have a dog or even if you live in the country at all and don't have your garden securely fenced, one time or another you have eaten veggies that have been peed upon, peed around, peed at.
Pee is pee....horse pee, cow pee, deer pee, sheep pee, or goat pee...it eventually gets put on a garden somewhere in the load of manure that gets mixed in and sometime or other we have all consumed food grown in pee.
One of the main ingredients in commercial fertilizers is urea.
What one has to understand is that people don't just dump a load of pee on a veggie and then go eat it...the substance is poured at the base of the plant during times of high nitrogen needs...usually NOT when the plant is bearing fruit but when it is in its first growth.
The subsequent rains, filtering by the soil, etc. dilutes this substance and brings it down to where the root system can actually utilize it. The roots do not act as little straws that suck pee into their stems to place it directly into the fruit you will be eating, so if that all consuming image of pee in your food is the sticking point, one only has to educate oneself about how nutrients are utilized and broken down by plant life.
It's a nutrient, like any other nutrient in the soil...time to get over it.
