New research suggests that disease-causing amoebas that live on organic leafy vegetables can shelter human pathogens like Pseudomonas, Salmonella, and Helicobacter and are a potential risk to public health.
Foodborne illness from consuming contaminated fresh produce is common and can have serious effects on human health, especially when eaten raw. During growth, harvest, transportation and further processing and handling, fresh produce can be contaminated with pathogens from human or animal sources, through contact with soil, irrigation water, air, rain, insects, and during industrial produce-washing.
Vegetables can become contaminated with certain protozoa (single-celled organisms) such as free-living amoebae (FLA), that feed on bacteria and can act as hosts to pathogenic bacteria (the so-called "Trojan horses") which resist FLA digestion and could be a threat to public health.
The main bacterial types identified were Flavobacterium (found in 10% of vegetable samples) and Pseudomonas (10%), many of which do not cause disease in humans. However, a third of samples (34%) contained 52 potentially disease-causing types of bacteria including Legionella, Salmonella, and Arcobacter. The resulting infections can cause pneumonia and gastrointestinal illness.
Moreover, the FLA species Vermamoeba vermiformis that commonly causes severe infections in humans was found in a fifth (19%) of vegetable samples; and Acanthamoeba castellanii, that can cause blindness and encephalitis were identified in almost two thirds (63%) of samples.
"The presence of bacteria contained inside the free-living amoebae suggests that they are vehicles that can easily transmit pathogens capable of reaching humans and causing health problems through contaminated organic vegetables", says Dr. Moreno. "Contamination can arise as a consequence of treating soil with organic fertilizers such as manure and sewage sludge and from irrigation water. Leafy greens are particularly susceptible to fecal contamination due to their proximity to the ground and the likelihood of humans consuming them without cooking."

Which is why I avoid organic foods like the plague.
Those things are a fake-looking Orange color.
I can almost always tell them apart from a real tomato.
Personally, I prefer the tomatoes we grow in our own garden. My second choice are the Roma tomatoes that cost half as much per pound as the big beautiful ones at the store. The Roma tomatoes we get at the grocery store typically taste better than the “organic” labeled ones. I know this from experience.
I guess thought that a lot of people can be convinced that the crappy looking over priced tomatoes taste better because of some sort of psychological effect. If someone told them the regular store bought tomatoes were organic would they be able to tell the difference? I can tell you from cooking at a fire station for 25 years that they definitely cannot. My guess is that you are no different.
Sorry typo:

[Organic food doesn’t have the pesticide and herbicide residue, but may harbor pathogens not normally present when eating non-organic food. ]
Apparently *organic* is often not as organic as implied.
That was the ( I guess very old ) overloaded chicken truck at the weigh scales joke I was referencing.
I hate to tell you, the food grade hydrogen peroxide might kill the tiny slugs that carry Rat lung worm disease, sometimes found in leafy organic vegetables, but if you eat their little dead carcasses in your salad you could still get sick and die.
Funny, I saw no mention of migratory workers crapping in the fields while they harvest.
E. coli and a few other pathogens are prevalent. Organic also means more land and water needed to grow. It’s a trade off.
You can miss all the scales by going over Wolf Creek Pass.
This is a situation where you trust agriculture crops to be grown without chemical fertilizers, pesticides, or herbicides.
Organiclly grown soil tilth depends on where and what 'natural fertilizers' and green manure crops are grown, and then 'turned under'.
Many farmers have been known to use 'waste water treatment plant' sludge which would include any of these human disease pathogens as fertilizers.
Unless treatment plant sludge is fully composted and heated, many of these same human pathogens could well be infecting whatever crops are being grown.
However, treatment plant sludge may also includes heavy metals : lead, agriculture run-off, arsenic, etc.
Technically, human manure ('Night Soil') is organic.

Crud, I missed that one.
Thank you!
OK, to get an over loaded chicken truck across the scales you bang on the side of the truck and weigh it when the chickens are flying in their cages.
Best shot is to grow your own.
Well, I was referring to that old C. W. McCall song, but all right.
Good idea!
What makes you think that?
