<p>[QUOTE=&quot;desertgem, post: 765540, member: 15199&quot;]EDTA is also used in the preparation of many food stuffs that might chemically react with metal ions from the can or lid. It is in soda, mayonaise, canned fruits and vegetables, etc. Since many cans are now lined, there might be less need for this, but EDTA ( calcium) is used for heavy metal chelation for poisonings such as mercury. Microoganisms and humans have many enzymes that require a metal component. Excess amounts of EDTA can inactivate these enzymes and kill microorganisms such as those use to breakdown sewage. The CDC also has recorded where use medically of EDTA ( sodium) was used in error and was implicated in a few deaths, but no listed deaths from use in food stuffs. </p><p><br /></p><p>EDTA can be used in &quot;cleaning&quot; coins, but it is not suggested, especially for copper coins unless you have a high knowledge of chemistry. EDTA will be used more in medical treatment, as new evidence show that a small amount can be as active as aspirin in reducing blood clotting, and that by conjugating it with antibiotics such as Amoxicillin can increase it&#039;s effectiveness in combating MRSA and VRSA infections which have become more widespread in the &quot;civilian&quot; ( non hospital) population.</p><p><br /></p><p>It is doubtful that there is enough EDTA in a can of soda to cause a reaction with coins. I would expect it is the carbonic acid that would cause most of the problem, but yes, keep sodas away from coins.</p><p><br /></p><p>Jim</p><p><br /></p><p>p.s.
