Uv works to treat, but then you need chlorine for residual effects--to keep bacteria levels low. hlthe2b Apr 2012 #19

meat, but surely there's got to be a better way than ammonia?

Or maybe not, but at least, it should be included as a warning on every bit of meat sold.

It really should have been called cold pasteurization or something of that nature because so many misunderstand what is going on--which is only killing microbes.

The is the solution for beef no doubt. Though it does NOT replace good management and processing practices. Much of the problem with E. coli O157:H7 and other pathogens is very poor management and handling practices from ranch to slaughterhouse to processing plant and to the table.

UV has been used commercially for many years in
the pharmaceutical, cosmetic, beverage, and electronics
industries. It was used for drinking water disinfection
in the early 1900s but was abandoned due to high
operating costs, unreliable equipment, and the expanding
popularity of disinfection by chlorination. Recently,
the safety of chlorination has been questioned
and UV has experienced increased acceptance in both
municipal and household systems. There are few
large-scale UV water treatment plants in the United
States although there are several such plants in
Europe.

Municipal systems use UV in conjunction with chlorine,
thus reducing the amount of chlorine necessary
for disinfection. Likewise, disinfection byproducts
(DBPs), the chemicals associated with chlorination,
are also reduced. Certain DBPs, such as trihalomethanes,
have been linked to increases in certain
cancers. UV treatment’s main advantage is that no
chemical input is required. However, UV treatment
lacks residual (remaining) disinfection in the water
delivery system, such as that available with a chemical
treatment system like chlorination. Therefore, a secondary
disinfection method, such as chlorine or ozone
may be a requirement for a UV system.

A lot of factors affect the effectiveness of a UV system, and it's possible that the design of the pool filters you mention was inadequate. Perhaps the UV light wasn't intense enough to zap algae, for example. From the paper I cited, post-treatment with some amount of chlorine may be necessary, but it's less than the amount used for full treatment.

I am building my off-grid cabin's rain water system now and I know UV is expensive... and there are limitations... the water needs to be filtered first...

and UV disinfected water can become re-infected downstream... with the state of many water systems this is probably a big concern... chlorine continues to disinfect downstream.

for my personal system based on my usage UV's not really an option... I'm going with chlorine in the large tanks of pre-filtered rainwater (just of large sediment and debris with a pre-settling tank) and filtering down to .02 microns with a carbon filter to remove the chlorine... should do... I think...

that addresses the concern of downstream reinfection. Also, it stands to reason that upstream filtration before chlorination may remove certain organic molecules that combine with chlorine to produce carcinogenic compounds.

We have a freezer full of beef, a whole cow actually, grass fed, butchered and cut up with nothing added to it.

What is the reasoning behind adding the ammonia?

Don't forget to get a shower head filter too. Standing in a stall with hot chlorinated water cascading over you, is a great way to absorb even more!

But I agree with your point - all the crap that is in our environment & our food that we are not told about. The government won't even make food manufacturers list GMO ingredients on the labels.

Every vital institution in this country is corrupt through & through, thanks to our everything-for-profit model.

They drip toxins in our water, up to the fed limit. this is a nifty way to get rid of poisins. Hell, Flouride was an industrial pollutant, that had no use, till they invented one.
