It is concerning and unnecessary, but keep in mind arsenic is found in many places, including seeds and nuts.

For the curious...


The main sources of exposure to arsenic for humans are environmental and dietary. Much of our intake comes through foods but not all forms of arsenic are toxic. An ion chromatography-inductively coupled plasma mass spectrometry method has been used to determine the different forms of arsenic in edible nuts...

...Arsenic is the twentieth most abundant element on Earth,...

...The group of organo-arsenic compounds that includes arsenobetaine, monomethylarsonic acid (MMA) AND dimethylarsinic acid (DMA) are essentially non-toxic but the inorganic forms, As(III) and As(V) are quite toxic...

so which do the chickens get?

...The main routes of human exposure are by eating arsenic-containing foods...
...Much of the arsenic naturally found in food is the "safe" form although foods can also be contaminated with toxic arsenic from pesticides, environmental pollution or tainted water supplies, such as polluted wells, as reported recently in Spectral Lines, Issue 20. From February 2002, the EPA reduced the acceptable level of arsenic in water in the USA from 50 to 10 ppb, reflecting concerns about public health...

...Consumers recognise that nuts are a healthy product with high nutritional value, but do they also contain unhealthy levels of arsenic? Almonds, Brazil nuts, cashews, peanuts, pine nuts, walnuts, pistachio nuts and sunflower seeds were selected....

...The main species found in the oil extracts were As(III) and As(V), the toxic forms, but their levels were relatively low (0.7-12.7 and 0.5-4.3 ng/g, respectively), on a par with those found in other plants. The amounts of As(III) tended to be higher in non-processed nuts (cashews, almonds, pine nuts, walnuts) than in processed samples (salted peanuts, sunflower seeds). Since As(III) is the more toxic form, there is one way to cut down daily arsenic intake if you still like to eat nuts...


CCA pressure-treated wood contains arsenic which can be released from the wood when the wood is burned, through mechanical abrasion (like sanding or sawing), direct contact and when acid contacts the treated lumber. See the 'CCA Wood' tab to the left for more information. Incineration of CCA pressure treated wood does not destroy arsenic. It is illegal to burn CCA wood in all 50 states. Some countries in Europe have banned CCA wood and its use is being reviewed by the whole European Union. It is incredible, but a single 12 foot 2 x 6 contains about 27 grams of Arsenic - enough arsenic to kill more than 200 adults. A tablespoon (about 20 grams) of CCA wood ash has enough arsenic to kill an adult human...

a Wisconsin family who burned CCA scraps in their home furnace for winter heating. Their hair fell out, all suffered severe, recurring nosebleeds, extreme fatigue and debilitating headaches. The parents complained about 'blacking out' for periods of several hours, followed by long periods of extreme disorientation. Both children suffered frequent seizures described as 'grand mal'. The symptoms were finally traced to breathing minute amounts of arsenic laden dust leaking from the furnace as fly ash. The family's houseplants and fish died, too, victims of copper poisoning from the same dust. ...

...Exposure to high levels of inorganic arsenic - greater than 100 ppm parts of arsenic in food or water - can also be fatal. Arsenic and arsenic compounds are known cancer-causing agents and have been implicated in lung and skin cancer and associated with birth defects. While organic arsenic (arsenic combined with carbon compounds) is less toxic it causes similar effects....

I saw this quote somewhere, but did not bother to see how true it seemed....

Fluoride is one of the most toxic substances on earth, on par with arsenic and lead

Happy Living ;-)
