Furan induction of DNA cross-linking and strand breaks in turkey fetal liver in comparison to 1,3-propanediol

► Furan reduced the %DNA in comet tails of turkey egg hepatocytes at 24 h. ► Finding of reduced comet tails indicates DNA-protein crosslinks. ► Proteinase digestion increased comet tails, showing DNA strand breaks. ► 1,3-Propanediol (PD) was not toxic and induced DNA-protein crosslinks. ► Furan and PD produced DNA damage in turkey egg hepatocytes.
