Arcobacter butzleri is one of the aerotolerant Campylobacter species which cause persistent diarrhea, abdominal pain, nausea and vomiting in human. The aim of this study was to determine the growth and survival of A. butzleri under the heat treatment or freezing storage condition. In heat treatment, two Korean isolates of A. butzleri were treated at 40 to 80oC for various times. In freeze treatment, two Korean isolates of A. butzleri were kept at 4, ?20 and ?70oC from 1 to 15 d. The survivability of the A. butzleri Korean isolates significantly decreased at higher than 60oC heating condition but it didn’t show any significant difference in 40oC treated group. Under the cold stress condition, survivability of A. butzleri were significantly decreased at ?20oC storage. Like other foodborne pathogens, survivability of A. butzleri was controlled by heat and freezing treatment.
