I suppose if there were pathogens in the dirt on the surface of the veggie, you could wash them away. If they are internal to the veggie, you are out of luck.

Some pathogens adhere tightly to the surface of the food. They also get into crevices, especially in greens, and are practically impossible to remove.

Btw, did you know that the human body is 90 percent bacteria and 10 percent human cells?

Does Washing Fruits and Vegetables Make Them Safe?
Thanks for the link. So, you can wash some of the microorganisms off, but you won't necessarily get them all off.

I had no idea that it was that much.

I read that poop is almost all bacteria, not what's left after food is digested. I still figure it's mostly what's left after the food is digested. It's just inside bacteria now.

That depends on how much indigestible fiber you eat

That article doesn't differentiate between soluble and insoluble fiber: http://www.m.webmd.com/diet/features...-soluble-fiber

I wont challenge that at the moment. Don't have the time right now to research it.

Here is the USDA page on fruits and vegetables:

Raw Produce: Selecting and Serving it Safely

I realize you have linked info supporting your statement in another thread and I'll get to it eventually...I have a job and a business on top of gardens to deal with but I am interested in reading it.

BUT the USDA does refer the activity of washing as "reducing" bacteria. Here is a quote from that page "Dry produce with a clean cloth towel or paper towel to further reduce bacteria that may be present".

I'm not a doctor or a scientist, but maybe there is something to reducing bacteria through the action of washing...that consuming large amounts of bacteria is a greater likelihood of illness than smaller amounts. This would support that you in fact DO "reduce" bacteria by washing, BUT in the line of thought you have put forward, you can never get it "all" off.

Why would the USDA say this? if washing vegetables and fruit did nothing to reduce bacteria, washing would be to simply remove debris that would change the taste or texture of the food...like grit for instance. So if there is nothing visible, or texturally evident, washing would be pointless.

I have always said we all need some bacteria to keep our immune systems on the job. In fact, I make KimChee and will be working on sauerkraut here soon and just did my first real crock dill pickles. That is an example of purposely encouraging bacteria...beneficial bacteria!

A pathogen is a biological agent that can cause disease or illness in it's host. it may be bacterial or viral in origin. not all bacteria are pathogens. So maybe washing can remove some of the pathogens that are bacteria, but not pathogens that are not bacteria.

I didn't say it wouldn't do anything. Reduce is not the same as eliminate.

Trust me, I know what bacteria and pathogens are. I worked at a medical school for 14 years and became a master gardener two years ago. I research nutrition and food safety constantly because I have medical conditions that reduce my body's ability to absorb nutrients from food. I also have a food handler's certificate from a class in culinary school three years ago (I had to withdraw because of medical issues). I still have the book from that class.

That's an impressive resume. I was not challenging your background...we don't know each other enough to even think of such a thing.

Your comment was "you cannot wash pathogens off of raw produce". That's all I saw, I hadn't read your links above like I said. For some reason I thought they were in another thread. At least they are here so I can easily come back and read that info. Knowledge is a good thing.

Also, sorry to read about the medical issues. Gotta be tough.
