Which wood finishes for food surfaces?

Q. We purchased an old wooden high chair that we'd like to refinish for our baby. What type of finish would be safest to use?

A. Because ingredients in wood finishes can migrate into foods, only use those that meet Food & Drug Administration regulations as indirect food additives. Made of linseed oil (from flax seed) and beeswax, several finishes by Tried & True (Original Wood Finish, Varnish Oil and Danish Oil Finish) can be used safely on furniture and kitchenware. Unlike most linseed oil finishes, they contain no heavy metal drying agents. Remember to ventilate when applying, and soak rags in water after application to prevent combustion.

Kitchen stores generally recommend mineral oil for conditioning wood salad bowls and cutting boards, but there is insufficient evidence on its safety. Vegetable oils, such as walnut oil and olive oil, can be used as wood finishes, though they must be reapplied often and can spoil over time, causing a slightly musty smell.
