Food sold in recycled cardboard packaging 'poses risk

Researchers found toxic chemicals from recycled newspapers had contaminated food sold in many cardboard cartons.
The chemicals, known as mineral oils, come from printing inks.
Cereal firm Jordans has stopped using recycled cardboard and other firms are to ensure their recycled packaging does not contain any toxic oils.
Kellogg's and Weetabix said they were taking steps to reduce the amount of mineral oil in their packaging.
Exposure to mineral oils has been linked to inflammation of internal organs and cancer.
Government scientists in Switzerland found quantities of mineral oils between 10 and 100 times above the agreed limit in foods like pasta, rice and cereals sold in cartons made from recycled cardboard.

Terry DonohoeFood Standards AgencyIn one scientific paper they describe the potential for mineral oils to migrate into foodstuffs as "frightening".
However, the Swiss food safety authorities have concluded that consumers who eat a balanced and varied diet have no need to worry.
In a statement Jordans said that, as an environmentally responsible company which had previously used largely recycled packaging, it had taken the decision to abandon it reluctantly, but felt it was sensible.
The BBC investigation found other food companies were aware of the issue - but none had so far followed Jordans' lead.
More than half the cardboard used in Europe is made from recycled materials.
So-called "virgin board" from newly harvested trees is more expensive and there is not enough of it to replace recycled card completely.
The research has been led by Dr Koni Grob at the government-run food safety laboratory of the Canton of Zurich.
In one study for the German food ministry last year he and his colleagues tested a sample of 119 products bought from German supermarkets.
They found mineral oils passed easily through many of the inner bags used to keep food dry and fresh.

Reducing Your Water Bills With a Water Meter

Water is must for us and we can't survive without it, however the growing population has made it difficult for the authorities to supply adequate water for all. In this scenario, as users we should take some concrete steps to reduce the consumption of water as much as possible. Saving water helps not only in reducing bills but it also conserves the environment.
The key advantage one could obtain with a water meter is that the bill will be charged against the actual use. Normally before, the same amount of bill is charged to all irrespective of the quantity consumed. So installation of a water meter encourages families to take genuine measures to make key lifestyle changes which involves taking a shower instead of having a bath, flushing the toilet less regularly, turning off the tap while brushing teeth, avoiding the use of a garden sprinkler system, fitting a new washer on dripping taps, using the washing machine or dish washer only when there is a full load and many other such steps. These will in the process minimize consumption and save money.
As per experts the average metered water bill is $445 in comparison to $535 for that of unmetered bill. The stats reveal that water meter can bring about 20% savings in monthly bill. This saving is brought by the conscious effort put forward by the users to save water and the environment.

The studies by the Environmental Agencies have shown that the ground water levels are the lowest in 20 years. The average family use of water in developed countries is 153 liters of water everyday whereas their developing counterparts are contented with only 20 liters a day. Since we use the water more it is our responsibility to save it.

Buying and Using Water

Water is purchased much the same way we purchase electricity. A meter measures the range of gallons that enters the water program, either in cubic feet or in hundreds of gallons. The meter, which isn't equipped to record the huge numbers used by most foodservice locations, will show a basic range.
 
 
The meter reader takes that range and multiplies it by a constant figure, known as the constant multiplier. For instance, if the meter shows 1200 and the multiplier is 100, we have consumed 120,000 gallons. Whenever you turn on a sink in your kitchen, the drinking water rushes out at 50 to 100 psi. This stress is a lot more than sufficient to get it from the city's pipes to the building, which only takes up to 20 psi.
The excess pressure is used to move drinking water into numerous pipes throughout the facility. his is called the upfeed system of getting water. Actually, 50 to 100 psi is strong enough to supply water to the upstairs area of a making four to six stories high. If your facility is in a taller making than that, you'll most likely require water pumps to boost the stress and flow.
 
 Water meter,Water meters, Woltman Water Meter, Single Jet Water Meter, Multi Jet Water Meter,Piston (Volumetric) Water Meter,
 
Pumps could be utilized to increase drinking water stress; valves (called regulation valves) can be utilized to decrease it. Your goal is to control the drinking water coming into your facility to avoid fluctuating pressure or an uneven flow rate. And whenever there's a possibility that contaminated drinking water could backflow into the potable water program, a backflow preventor should be installed.
 
 
Backflow may occur whenever a piece of equipment, such as a commercial dishwasher, is capable of creating stress that is greater than the incoming pressure of its supply line. The segments from the typical upfeed program are:
Water meter: The device that records water consumption. It is the last point of the public drinking water utility's service. Anything on "your" side from the drinking water meter, including all pipes and maintenance, is your responsibility, not the water company's.
 
 
Service pipe: The primary supply line between the meter and the building.
Fixture branch: A pipe that carries drinking water to a single fixture. It could be vertical or horizontal and carry warm or cold drinking water.
Riser: A vertical pipe that extends 20 or a lot more feet. It can carry warm or cold water.

White With Black Stripes?

White With Black Stripes?Once there were two zebras. One zebra asked the other:
"Am I white with black stripes or black with white stripes?"

The other replied:
"Ask God."

That night before the first zebra went to bed, he prayed. God replied:
"You are what you are."

The zebra was confused by this, and the next day, he asked the second zebra what it meant. He replied:

"I gues you are white with black stripes, otherwise he would have said 'Yo is what yo is.' "

Nurse Jody Makes Housecalls By E-Bike

Nurse Jody Makes Housecalls By E-BikeRegistered nurse Jody Hoppis wanted more time with her patients, and a schedule that would accomodate her life as a working mom of three. So she ditched her job at a family practice clinic and set up her own nursing practice calledmymobilemedicine, of medical house calls made exclusively by electric bicycle.

Photo stills courtesyKomo News.Hoppis bikes in a 15-mile radius around the town of Bellingham, Washington, making house calls to individual patients.Hoppis carries all of her equipment - a laptop computer and a "diagnostic bag" with stethescope and blood pressure reader - in a custom-made bright orange bike trailer. It is modeled on a waterproof (and lockable) trailer used by Scottish postal carriers. HerKalkhoff Pro Connect Sporte-bike provides a bit of extra power for making her rounds.Hoppis told theBellingham Heraldthat her bike-based business cuts out a lot of the overhead of a regular office, and she can not only see patients quickly as they call or e-mail requesting a visit, but spend more time with them than a busy medical office.She makes nearly all of her patient visits by e-bike, and her Mobile Medicine web site spells out her medical philosophy, which is to treat patient symptoms, rather than just work from diagnostic tests.It¡¯s always great to see people expanding the role of bikes in making viable businesses.
