A must see!!!!! Check out this movie.

Ingredients in food that are added by design

- Aspartame, a fecal matter of E.coli,  that causes brain cancer, threat to inborn and so many health effects, it’s just unspeakable.

- Plastic in nuggets, and many kinds of TV meals

- Fluoride in water, a form of forced medication

- Corn that grows its own pesticide in it, linked to organ failure and sterility.

- Genetically modified meat like salmon…

And many many more.

Sugars play key role in bacterial infection in humans

Sugars play key role in bacterial infection in humans: Study.

March 18, 2011 – Melbourne

Australian researchers have revealed that sugars that change their shape with temperature could be a key to bacterial infection in humans.

The findings could lead to new ways to treat and prevent gastroenteritis without relying on Antibiotics, reports ABC Science.

Bacterial geneticist Victoria Korolik of Griffith University’s Institute for Glycomics and colleagues have been looking closely at how the bacteria Campylobacter jejuni infects gut cells in animals and humans.

“This is the most frequent cause of any gastrointestinal illness around the world,” she said.

The bacteria are a normal part of a chicken’s gut flora and only cause disease in humans and higher primates, typically through contaminated food.

The bacteria also cause the auto-immune disease Guillain-Barre syndrome, in which the immune system kills off the body’s own nerve cells.

Two years ago, Korolik and team, including senior researcher Christopher Day, published key findings that provided the first clue to understanding why humans but not chickens are vulnerable to the bacteria.

The researchers now analysed the binding of the bacteria to a different range of glycans (sugars), which typically occur in the gut cells of animals and humans.

They found that when grown at 37 degree Celsius (the body temperature of humans), C. jejuni bound to a range of sugars more common in mammals, but when it was grown at 42 degree Celsius (the body temperature of chickens), the bacteria bound to a different range of sugars more common in chickens.

In both chicks and tissue culture studies, the researchers have found the sugars seem to change their shape at different temperatures to suit the host they are in.

Temperature also affects the proteins on the surface of the bacteria, but in a different way.

Korolik said if her team could confirm that the proteins and sugars they’ve identified enable the C. jejuni infection of humans, they could develop therapeutic molecules that can block the binding.

She said therapeutics could be added to chicken feed to reduce bacterial infection and be given to humans as a preventative or treatment for infection.

She also said the interaction between sugars in bacteria and human gut cells is also important in responding to the rare Guillain-Barre syndrome.

The interactions between sugars in bacteria and human gut cells may also have broader implications for research into treatments for food-borne infectious disease, said Korolik.

For treatment of bacterial-related food-borne disease, the research could provide alternatives to Antibiotics, which is important given the problem of antibiotic resistance, she added.

The study is appearing in PLoS ONE.

World Consumer Day at AUB… very interesting!

“Participants at AUB symposium on food safety urge consumers to complain in defense of their rights” - Beirut, Lebanon- 15/03/2011

World Consumer Day at AUB, you can check photos on the very important facebook page: LAFS – Lebanese Association for Food Safety

Among the directorate’s (the Directorate of Consumer Rights) top achievements is the creation of a complaints hotline reached on call center number 1739, which allows consumers to tip off the directorate of any foul play.

Fleifel considers the preliminary feedback on the hotline as highly positive, saying that whereas consumers would not dare tip off the directorate prior to the creation of the hotline, now more than 1300 serious complaints are being processed per year, 87 percent of which are being successfully resolved. Fleifel noted that more than 45 percent of complaints are food-safety-related.

As a result of its efforts and studies, the ministry has recently banned the import of three unsafe products: baby bottles containing Bisphenol A, a toxic substance used in some plastics; Bull shot, an energy product that is sniffed and is said to promote the consumption of drugs; and Healthy Shisha, a nargileh brand that was shown to be more harmful to health than regular nargilehs or cigarettes, themselves established to cause cancer. The good news is that the directorate is building its capacities and is now hooked onto a global alert system that automatically informs it of any additions to the database of banned or revoked products.


Raw-Milk Cheese, how bad can they be?

Posted on

Many cheeses in Lebanon are sold as “baladi”, and most of them have not undergone pasteurization. How safe are they?

If you would like to know more about the subject, read this article:

Is 60-Day Rule Still Valid for Raw-Milk Cheese?.

Recent recalls of raw-milk cheese have drawn increased attention to the U.S. Food and Drug Administration (FDA) rule that requires cheese made from unpasteurized milk to age for a minimum of 60 days before sale. For more than a decade, both the FDA and numerous food research groups have been working to answer the question: Is the “60-day rule” effective at eliminating harmful pathogens from raw-milk cheese?
The short answer seems to be, “Not completely.” The FDA is considering a possible change to the rule.
When the FDA first enacted the 60-day rule in 1949, no known disease-causing pathogens could survive the acidifying process of aging for more than a portion of the two-month process, and the 60-day time frame was selected to include an additional margin of safety.
Half a century later, however, modern studies and illness outbreaks have shown that some harmful pathogens survive in raw-milk cheese for longer than 60 days. A study published in the December 2010 Journal of Food Protection found that a strain of E. coli O157:H7 survived at viable numbers for approximately 100 days in Gouda and cheddar cheese, while researchers detected trace amounts after more than 270 days.
In November, an E. coli outbreak that sickened 38 people in five states was traced to Bravo Farms’ Gouda cheese made from raw milk and aged for at least 60 days. In December, gourmet raw-milk cheese from Sally Jackson in Washington state was the source of eight E. coli infections.
“We didn’t have this problem 50 years ago,” said Kathy Glass, Ph.D., associate director of the University of Wisconsin-Madison’s Food Research Institute. “At the time, the 60-day rule made sense, but now we have new enemies in front of us and we need to have a different tactic.”
The FDA has had the regulation under review for more than a decade. According to FDA spokesperson Sebastian Cianci, research questioning the effectiveness of the 60-day timeline first came to the agency’s attention in the late 1990s, but regulatory resources were focused on other matters in subsequent years.
The agency has since completed the initial draft of its review of the rule, although Cianci could not specify a timeframe for any decisions regarding it. He said the rule has been under review “in earnest” for the past year and he called the delay helpful in allowing time for more researchers to investigate the issue.
Researchers and cheese makers alike now speculate over what a revision to the law might entail. Glass suspects that the 60-day rule could become the “90-day rule” or the “120-day rule”.
“The holding time works because of a combination of acidification and not having enough moisture. There’s definitely a science behind it,” she said. “E. coli is very acid-resistant and has a low infectious dose, but if you give it enough time it will still die off under otherwise good conditions.”
Julie Steil, owner of River Valley Cheese in Fall City, WA, produces and sells a variety of cheeses made from both raw and pasteurized milk. She designs her raw-milk cheeses around the 60-day rule and said an extension of the minimum aging time would immediately impact her cash-flow and cheese-making process.
“I make a raw-milk Tomme-style cheese and have perfected my recipes so the cheese peaks at 75 to 90 days,” she said. “If the cheese sits on the shelf aging longer than that, it will be ruined.”
Aging extensions would reduce the shelf life of cheeses and increase the cost of holding inventory while it ages, Steil said. Her customers actively seek out River Valley’s raw-milk cheese for what she described as its “less processed” flavor.
Others question whether the emphasis on aging time is the best approach to controlling harmful pathogens in raw milk products. In countries such as France, Germany and England, sale of raw-milk cheese requires no minimum aging time. Instead, safety measures focus on animal health requirements, hygienic milk collection and storage, fast cooling, and microbiological criteria (a maximum acceptable concentration of coliform bacteria). As with raw milk products sold in the U.S., those sold in these countries carry a specific label that usually explains the health risks associated with consumption.
Of the 28 U.S. states that do not prohibit raw milk sales, many–including Washington, Idaho and California–have implemented microbiological criteria similar to regulations in Europe. Still, public health authorities such as the Centers for Disease Control and Prevention and food research professionals such as Glass stress caution when consuming raw milk products, even those aged to 60 days.
“When I teach dairy safety classes, I’m quite clear to people that even though the regulations say ’60 days’, there are some cheeses that just might not be safe to make with raw milk–they’re going to need heat treatment,” Glass said. “But when you get the right cheese, like a two-year-old Parmesan made from raw milk, it’s so good. I do the necessary tests and know a bug won’t stand a chance in something like that.”

 

Bananas get second skin :)

Del Monte packaging: Bananas get second skin | Mail Online.

Mother Nature may have thought she came up with the perfect packaging for the banana, but the man from Del Monte has other ideas.

The company has taken the view the yellow skin is not quite enough, and will sell individually-wrapped bananas at petrol stations, convenience stores, leisure centres and gyms.

The Del Monte bananas will be marketed under the slogan ‘Natural Energy Snack on the Go’.

It's a wrap: The Del Monte bananas are likely to sell for considerably more than the loose price of around 15 pence

It’s a wrap: The Del Monte bananas are likely to sell for considerably more than the loose price of around 15 pence

The price has not yet been revealed, but is likely to be significantly higher than the cost of buying a loose banana at a supermarket – typically around 15p.

While the trial may seem bizarre at a time when big businesses are under pressure to reduce packaging waste, Del Monte insists the addition of a clear plastic bag is actually a green measure.

The company claims that the bag contains ‘Controlled Ripening Technology’ – which extends the shelf-life of the banana by up to six days.

The banana is put into the plastic bag when it is green and, according to the manufacturers, goes on to ripen more slowly than if it had been left in the open air.

The product is also being trialled in the U.S. where the  wrapped bananas are selling for one dollar each – around 62p.

‘Nature has designed out the need for bananas to have extra packaging even for sale at service stations. It’s the same yellow wrapper that protects them on the supermarket shelf.Gary Porter, of the Environment Board of the Local Government Association, said: ‘The man from Del Monte should say no. This is a backwards step which will contribute to the twin problems of landfill and litter.

‘Retailers and manufacturers need to cut back on packaging, not create more.

‘Every year it costs councils more than £600million in taxes to send waste to landfill. Councils and residents have made great steps in bringing that cost down by increasing recycling but we need the food industry to do much more to reduce the amount of unnecessary packaging.’

James Harvey, Del Monte’s UK managing director, told the Fresh Produce Journal: ‘Del Monte’s new CRT packaging is designed to provide significant carbon footprint savings by reducing the frequency of deliveries and the amount of waste going to landfill. The packaging is also recyclable.

‘It is a great product and consumer feedback shows a marked taste benefit too.’
