Apparently tubers are treated with chlorpropham to prevent them from sprouting. This makes me always want to peel my tubers. On the other hand, http://pmep.cce.cornell.edu/profiles/extoxnet/carbaryl-dicrotophos/chlorpropham-ext.html claims that you need 1000x the concentration found in potatoes to kill 50% of exposed rats.
So what do you think? Should we peel tubers or not? Aren't the vitamins and minerals supposed to be just under the skin?
Finally, I live in the EU and my potatoes do sprout in storage - does that mean they aren't treated in this way? Is there a law against it? Is sprouting a good test of tuber safety?

I personally peel them all the time. Chlorpropham or not, most tubers have all their natural toxins in the skin. If they aren't a staple, eating the skin once in a while won't be too much of a problem if they are organic.

If yours are sprouting, they're safe. If not, buy organic, from a grower who swears they're not treating them, and expect them to sprout within a week. Otherwise, peel them always.

A gardner I know told me that for potatoes it also depends on when they are harvested, if they are harvested while the plant in alive they have more toxins in the skin and they aren't as well as sprouting. Taken from a wilting plant they will probably already have eyes or will sprout very soon.

My store bought 'organic' yam will not sprout. I paid more for the organic ones only to find they may have been raised and harvested organically, then doused with Chlorpropham afterward? Doesn't that negate the label 'organic'?

Buying organic is the best option
