You're too kind. Keep in mind I am around things that if handled improperly could kill me off. I am an auto body painter. They may have taken the lead out of paint but the rest of the stuff is even scarier.
I do not think that lead poison is to be taken lightly, I just want you people to take it in context. What about the poor oysters? They have to live in a lead-lined shell
I agree with CARS, this needs to be taken in context. The article in JAMA that I cited said while there was concern, it was not toxic. They were making the point that it may be contributing to overall total dose of lead ingestion and was an area that could be looked at for removal of the naturally occuring lead. This certainly is a hot button issue. Most of the lead toxicity that I saw in Hematology/Oncology was industrial expsoure and mostly from fumes. I am sitting here writing this in my 175 year old home that has tons of lead. Our twins (now 8yrs old) were born with lead levels. They were monitored for two years with no problems in their development. Exposure in old homes comes mostly from dust that is omnipresent. Every time a window is opened or dust settles on anything, there is lead - much more lead than in oyster shells. You have to pick your battles as they say. If the level of lead in oyster shells is concerning, there are non natural forms of calcium supplementation that can be added to the feed but I am not savvy enough to know how much to put in. I have read threads here that say with layer feed you do not necessarily need oyster shells. Speaking of feed, what kind of calcium is in layer feed? The OP and others want to test their oyster shells but has anyone checked with the feed company to find out if their calcium supplement is contaminated? As I said earlier, I will continue to offer oyster shells to my hens. People have to pick their battles.
