UV light instead of pasteurization: it seems to work at least for calf feeding

Should milk fed to calves be pasteurized or UV treated? Or raw? Photo via Wikipedia. This work is licensed under the Creative Commons Attribution 2.5 License. Click image for source.

These stories are about treatment of on-farm milk for use in feeding calves. Of course, if it works for calves, why wouldn’t it work for people? Though probably the bar of surety is set higher when we’re dealing with food for humans. Michael Schmidt’s two-calf study comparing the effects of feeding calves raw milk vs store-bought pasteurized milk comes to mind as well, in connection with this news. Michael’s “Tale of Two Calves” remains the single most popular post ever published on The Bovine. Did you know that some farmers actually do pasteurize milk before feeding it to calves? Either that, or throw the “surplus” milk out and buy milk replacer from the feed store. You learn something every day. Thanks to Deb for the news tips: 

From New Scientist:

“AT A 3000-cow dairy farm near Ithaca, New York, Rodrigo Bicalho wrestles a 3-week-old calf onto a scale. The calf totters about; the scale reads 52 kilograms, a healthy weight. Bicalho makes a note. He is trying to find out what happens if he gives his calves milk that, instead of being pasteurised, is treated with ultraviolet light. Continue reading

Fluoride debate at London city council reminiscent of the pasteurization issue

From George Clark, QMI Agency, in the London Free Press:

“I was reminded last week of the social critic and stand-up comedian George Carlin. He was quoted as saying about causes that “Just because the monkey got off your back, doesn’t mean the circus has left town.”

Emotions ran high last week when city council debated the merits of possibly ending London’s fluoridation of water supplies. They hit their lowest point when councillors discovered material left on their desks linking the use of fluoride to Hitler’s death camps, to subdue and sterilize inmates.

It quickly became apparent the material was not from one of the opponents in the galleries, but from one of their own, Coun. Steve Orser. Orser did apologize to councillors offended by his action, but said it was sparked by his interest in such issues because his father had been a prisoner-of-war. The final vote was 10-5 in support of the ongoing use of fluoride. Continue reading

Is milk the carrier of Crohns disease?

We hear constant chatter from the regulatory types about the dangers of raw milk and the health hazards of consuming it. But they seem to be strangely uninterested in examining the health risks of consuming conventionally produced and processed milk products, not to mention many other processed foods. The L.A. Times article excerpted below gives a rare glimpse into one of the health hazards of conventional dairy products that we’re mostly not hearing much about. This article is from twelve years ago. One wonders whether any further research has been done since then to follow up on these significant findings. From Thomas H. Maugh II, in the L. A. Times, via Crohns.org:

“If, as some scientists are now convinced, Crohn’s disease is caused by a microorganism, the question becomes: How is it transmitted? The shocking answer, they say, is through that most sacrosanct of beverages–milk. The microorganism under suspicion, Mycobacterium avium subspecies paratuberculosis, or MAP, is common in U.S. dairy herds, activists argue, and it is not killed by conventional pasteurization.

Udder hysteria over raw milk dangers?

From the Hanover Evening Sun:

“As we sat down here to write, we were all ready to pour ourselves a nice tall, cold one. A big glass of raw milk. Surely, something that nutritious and natural couldn’t really be harmful.

Then, our research led us to the websites of the Centers for Disease Control and the Food and Drug Administration.

Whew. It’s a wonder we’re even around to have this discussion.

Considering all the dangers associated with raw milk, and considering that pasteurization didn’t become widespread until the 1950s, it’s a miracle that our parents and grandparents ever survived childhood. Continue reading

Contrasting Michael Schmidt’s pro-raw milk campaign to Women’s Institute founder’s pro-pasteurization campaign

From Tracey Tyler, Legal Affairs Reporter, in the Toronto Star:

Raw milk crusader Michael Schmidt at his Durham, Ont. farm, after a judge on Sept. 28, 2011 found him guilty of distributing raw milk. TRACEY TYLER/TORONTO STAR

“Before Michael Schmidt and his raw milk crusade, there was Adelaide Hunter Hoodless.

She isn’t mentioned in this week’s court ruling that convicted Schmidt of violating Ontario public health laws by selling unpasteurized milk. And her name leaves some of Schmidt’s followers looking perplexed.

But more than a century ago, after her youngest son, John, died from drinking contaminated milk as an infant, Hoodless embarked on a campaign to have all milk heat-treated — pasteurized — to kill potentially harmful bacteria, making her one of Canada’s earliest food safety proponents.

Food safety questions: can readers help

A reader who prefers not to be identified is asking The Bovine community whether anyone can answer the following questions regarding food safety:

  1. If pathogens exist in a particular batch of raw milk (for instance, salmonella, campylobacter or e-coli O157:H7), and those pathogens are then killed by pasteurization , what effect (if any) do the dead bacteria have on consumers who later drink that milk?
  2. In particular, if e-coli O157:H7 is liable to release “shiga-like toxins” is there some possibility that killing the e-coli via pasteurization might precipitate the release of such toxins into the pasteurized milk?
  3. Does anyone have information on the use of activated charcoal or bentonite clay as a remedy (and in particular, a handy home remedy) for any of the pathogens that might be found in raw milk?

Local Chicago ice cream makers may be shut down by the state for silly reasons

From Monica Eng and Chris Borrelli in the Chicago Tribune:

.

“A few years ago, Kris Swanberg, having been laid-off from her job as a Chicago Public School teacher, remembered she received an ice cream maker as a wedding gift. The Chicago mom fished it out of her kitchen cabinet and eventually started a new career.

Today Swanberg’s Nice Cream — on offer at local Whole Foods and farmers markets — is considered a star of Chicago’s rich and beloved artisanal ice cream scene, one that could be shut down entirely by state rules, she recently learned. Continue reading
