Just do a risk-reward analysis.  What is the risk of your daughter playing with one orange once and what is the added benefit of fun and learning with playing with an orange? Many people are ignorant of the *chemicals* (scary) that are used as pesticides.  Even if they are toxic or carcinogenic, they often degrade very quickly, and don't forget *the dose makes the poison*.  Oranges are one of the most toxic laden foods you can buy. That said, your child will be exposed to more poisonous and carcinogenic materials by simply being at a gas station while you fill your car than a lifetime of oranges can provide.  Don't let this lead to a lifetime of overparenting, what's life if you spend every moment maximizing survival?
