The recall stems from consumer reports of an uncharacteristic odor thought to be caused by trace amounts of TBA (2,4,6 tribromoanisole). TBA is a byproduct of a chemical preservative sometimes applied to wood often used in the construction of pallets on which materials are transported and stored.
While not considered to be toxic, TBA can generate an offensive odor and a small number of patients have reported temporary gastrointestinal symptoms.
