Chocolate, Lead and the Measurement Conundrum
- Chocolate, Lead and the Measurement Conundrum

Some chocolate contains lead. Is this safe? And does the ability to measure minute quantities of lead in chocolate make the product less safe?
This week's Risk Bites is about the measurement conundrum -- what do you do when you can measure what's in the stuff you eat to the nth degree? It's not primarily about the risks of lead in chocolate, but if you want to find out more about this, please check the links below.

Thanks to Mary Hall for the inspiration on using lead in chocolate as an example of the measurement conundrum.
