'does not harm the good bacteria in the stomach
You don't got good bacteria - or pretty much ANY bacteria - in your stomach...they're nearly all in your colon!.

Yeah, there are pretty much no bacteria in our stomachs, except for some acid loving menaces in unlucky individuals that are linked to peptic ulcers and cancer.

Helicobacter pylori is an example (http://en.wikipedia.org/wiki/Helicobacter_pylori).

Out of interest, and because it shows that one shouldn't be TOO skeptical about this:

Silver-N-Carboxymethyl Chitosan Nanocomposites: Synthesis and its Antibacterial Activities Nguyen Tien An1*, Nguyen Thi Dong1, Pham Thi Bich Hanh1, Tran Thi Y Nhi1, Duong Anh Vu1, Do Thi Nguyet Que2 and Do Truong Thien1
J Bioterr Biodef 1:102. doi:10.4172/2157-2526.1000102

Abstract
In this work, silver-N-carboxymethyl chitosan nanocomposites (Ag-N-CMC) were synthesized in the homogeneous state via the reduction of Ag+ (using [Ag(NH3)2]OH instead of AgNO3) by NaBH4 in the presence of water-soluble N-carboxymethyl chitosan as a stabilizer. The resulting Ag-N-CMG was characterized by FTIR, TEM and UV-vis spectra. The results showed that the average particle size of silver nanoparticles was little affected by the concentration of Ag+ added and was between 2 and 10nm. The characteristic surface plasmon resonance band of silver nanoparticles centered at about 398 - 410nm. In vitro antibacterial activities of Ag-N-CMC nanocomposites were evaluated against both gram-negative bacteria: Escherichia coli ATCC 25922 (Ec) and Pseudomonas aeruginosa VM201 (Pseu) and gram-positive bacteria: Staphylococcus aureus ATCC 1128 (Sta) and Bacillus cereus ATCC 9946 (Bc). The results shown that the Ag-N-CMC nanocomposites could inhibit the growth and multiplication of the tested bacteria.

Meaning that if the US government thinks it's reasonable...B-)

Just to show that there is some merit in silver as a disinfectant, Dec 2010's Scientific American has this from a news snippet on cheaply disinfecting water:

Silver works as an effective bactericide in part because silver ions damage genetic material.

Hi GCG,

What you got off the SABS website are the Permit numbers of SABS Mark holders. Before a company can claim to have the SABS Quality Mark, or put it on a product, the produsct must meet the criteria of the NAtional product specification, and the manufacturing Plant must be able to demonstrate their adherance to a Quality Management System, often ISO 9001. After successfull testing and inspection, a permit will be granted. Regular inspection and testing then takes place annually to confirm that everything is still acceptable (SANS = SA National Standards as opposed to the older "SA Bureau of Standards" / "SABS"). Aqua Salveo is a Trade name, and the product conforms to the requirements of SANS 1827. This specification is fo all products that can be used to treat water destined for human consumption.
