Would you buy tomatoes fertilized with urine?

Robert,
Up to about 10 years ago, I was promoting sanitation in a country town and district capital in Northern Uganda, called Adjumani. We called the approach a 'two track approach', one of the tracks was the promotion of ecological sanitation toilets, the other track consisted of a proper disposal (using wetlands) of the sludge coming from regular pit latrines:
Sanitation approach of GIZ in Adjumani town [font=Times New Roman, serif]
[/font] Privately built ecosan toilets (UDDTs) in Adjumani
Utilization of UDDT fertilizers in Adjumani
In the ecosan approach, urine separating toilets were constructed, and the urine could be used locally on people's private plots. For the solids, we constructed a small hand-operated composting facility, even though these could also be dug into the fields after a storage time of 6 months in the toilets.
More than 100 people decided to build an ecosan toilet using there own personal money. The town was only contributing some special plastic parts for urine diversion, which were brought from the capital Kampala. This shows that some people were quite enthusiastic constructing such toilets. Apart from the fertilizers, one main promoter of the ecosan toilets was that the maintenance was a lot cheaper than the one of pit latrines. For the latter, you needed to have a tanker truck to come every few years to empty the pit, which was very expensive in the local context, whereas for the ecosan toilets, emptying could be done manually. Of course, the ecosan toilets will only work well if properly constructed and properly maintained (possibly the two main drawbacks).
The attitudes of the population were generally positive, especially among the more traditional folks. But it's really a personal choice of each and every resident.

Yes, you're right, people are bemused about fertilizing urine.
But after explanation and demonstration they are enthusiastic.
It may be too early to also talk about feces also but with a special process of 9 months I obtain a magnificent compost.
My visitors handle it without discomfort
odorless, pathogen-free and very fertile.
It's much safer than the sewer system.Pathogens are eliminated without risk of propagation as in our sewers.
No danger in the garden also.
But for the moment I am content with the valorization of urine which provides 80% of the solution with minimal cost and savings.
One step at a time
See pictures.

PS: Let's say people tend to be bemused and amused about the use of urine as fertilizer, sorry for the confusion...

My experience would be that people tend to be bemused if I tell them that I am using urine to fertilize the fruits in my garden. That doesn't prevent them to pick the fruits, like currants, strawberries or apples.
In fact, I am using both stored urine and compost that I am also producing myself. The compost does not include feces, which are flushed into the drain. If I was including feces into the input of my compost, the reaction of visitors would possibly come out differently, depending, may-be, on how I would explain the process. But urine doesn't seem to be too much of an issue.
Best regards from my side,

I seem to recall seeing a neighbour's dog pee on their tomato plant. Is dog pee okay if human pee is not? Should I have told my neighbor?\
Should Bangladeshis be encouraged to drink the treated water of the Brahmaputra?
(Context explainer for people who don't know about the drinking water situation in Bangladesh: Having had the opportunity of two years in Bangladesh I came to wonder why their people prefer ground water to the water of the Brahmaputra. I could be wrong, but I was variously told that people won't drink Brahmaputra water because animals defecate in it. Many Bangladeshis drink, instead, arsenic-contaminated groundwater. I don't find it right, that people are getting arsenicosis while they could be getting treated surface water.)
All the best

Hello Paresh.
Very funny this video of the Big Bang Theory
I have the same results without TV drama faces.
The test made in Geneva during the Alternatiba event in September are all in French.
It is an eco festival with generally open minded people.
Basically I offered visitors the opportunity to taste tomatoes knowing that they were fertilized with urine.
I did the same type of tests at the WWW in Stockholm in 2019, in Swiss garden centers and during many events.
Then I offered them a second tomato and I asked them if they would buy these tomatoes at the supermarket.
100% of the opinions were favorable and quite impressed with the superior flavor.
It is a lot of fun to break the ice and do it a first time.
The people expressions are very easy to translate and the video also explains the precautions and my method of application.
My urine collection method with the ORIAZ Urinette avoids any risk of cross-contamination with faeces.
The Solar-Dripper ensures 100% application in the soil without contact with edible parts.
You can see another video translated in english :
This is an efficient and safe method to use in your home garden with you urine and for agriculture.
Farmer just have to be a bit more carefull ( ex: use glove) with collected urine to protech them from self exposure or splashing during handling.
More than 400 people have test my tomatoes so far and we have 0 % drama.
Handling your urine is 100 safe.
I encourage every ressearch groups to do it with at least 12 tomato plants.

Dear Robert,
For the benefit of people who don't know French, could you please summarise. I am also curious to know how people responded to your question.
In my understanding, even the most learned scientists find it yucky. I am reminded of this episode from the BIg Bang Theory.
Kind regards

I asked visitors to the Alternatiba fair if they would buy tomatoes fertilized with urine.
It was last week in Geneva.
