Is it safe to put fruit (with the skin on) on something painted with this product?

Happy to clear things up! All of Rust-Oleum paints, including Rust-Oleum Universal Spray Paint, are unleaded and safe for use on toys and furniture. The cautions on the cans refer to the liquid form of the paint and are driven by the solvents in the paint. Once the paint is fully cured, the solvents have evaporated and are no longer in the coating; the remaining coating is a combination of solids made of pigments and additives bound by the resin and can be considered non-hazardous. We do not, however, recommend this product for use on surfaces that will have direct contact with food or beverage.
