• The study compared laboratory toxicology testing (ToxCast) results with data from previous animal tests and epidemiological Trusted Sourcestudies.
• The ToxCast results and available animal study data confirmed that a common food preservative called tert-Butylhydroquinone (TBHQ) might negatively affect immune system functioning.
