Ok here is where you've found it, and typically pulled the statement apart as a good scientist would do.(fun intended:-)

From: Beneficial Bacteria

"Raw milk is a living food with amazing self-protective properties. As most food goes bad as it ages, raw milk gets better. From helpful bacterial fermentation, the digestibility of enzymes, vitamins, and minerals all increases."

eftfnc, you are correct and I need to apologise. The link you give does not direct to the article at all. It goes to someone’s blog. I couldn’t find the article anywhere on the blog at all, so ran a search and came up with this article http://www.naturalnews.com/023083.html Written by the same Jo Hartley and covering pretty much the same ground as what you posted. That is where the quote was.

As to argyria, it is the amount that is consumed that is the concern, not what size the particles are. It is a rare condition these days now that silver is no longer used as an antibiotic, but it still happens: http://dermatology.cdlib.org/111/case_reports/argyria/wadhera.html

Great stuff Agro, but if one was to have a closer look at the "subject at hand" than one would come up with:
http://www.ncbi.nlm.nih.gov/pubmed/18438688?ordinalpos=3&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum
and the links on the right in that page.
If you did look at the video presentation, you could surmise we are really talking "nano" here.

eftfnc, much of the time I do struggle to follow where you are going? What has a system of making nanoparticles of silver got to do with silver colloid related argyria? Are you suggesting that those suffering from argyria only got a problem because they consumed nanoparticles of the stuff? That is clearly wrong as the silver colloids are only microscopic and in at least two of the cases, it was silver mixed in solution that did the trick. Or are you suggesting that you are only using nanoparticles of silver and will therefore be immune to argyria? If you are using silver colloids, they are small but not quite nano.

And I didn’t look at the video, because I didn’t want to have to pay for it.

Sorry Agro, if I am confusing you by sounding confusing.I am not talking about Silver salts,where according to various articles Argyria was caused in a few people. I was talking about colloidal silver and nano silver which both are in liquid suspension. Almost all,I dare say all argyria cases were caused by homemade col.silver generators.I made one myself with the result that the fluid was hazy and did not use it because of it.That solution would have given me argyria as the particles were too large.Now the proper made c.silver is clear as water, as the particles are smaller.
The nano silver solution if you were to take a milk tanker full you still wouldn't get this argyria.I would advice you to look at this film because this chap explains it in full. No this url does not automatically rip a creditcard of ye'. Just click on the screen to watch and ignore the bottom bit, it will only cost you time.

eftfnc, the case studies included a variety of sources of silver: silver salts in solution, silver colloids, both home made and purchased over the internet. The factors that influenced development of argyria included the amount of total silver consumed and the ability of that silver to be absorbed into the body. The second is only a factor of form of silver, not size of particle. Smaller particle size will not save you from argyria unless you consume less silver total.

I find it somewhat strange that you are such an ardent consumer of organic food, but yet are happy to ingest something as unnatural as silver colloids.
