Eighteen non‐fasted, 12–16 week old pigs weighing between 20 and 40 kg were dosed with chloramphenicol intravenously at a dose rate of 22 mg/kg body weight. The pharmacokinetics of chloramphenicol were determined in blood plasma and sixteen selected organs and body fluids. The elimination half‐life in plasma was estimated to be 2.66pL1.06 h and volume of distribution was 1.39pL0.32 I/kg. The body clearance of chloramphenicol was estimated to be 6.64pL1.52 ml/kg/min. The elimination half‐life in tissue was found to range from 1.25 h in kidney to 5.89 h in fat. Most major organs ranged from 2.0 to 5.0 h. Significant correlations were found to exist between plasma concentrations and most major organ concentrations. Chloramphenicol concentrations in muscle, spleen, lung, stomach content, and large intestine content were found to exist slightly beyond the time when concentrations were negative in plasma. However, urine levels exceeded tissue levels at the last slaughter interval. It appears that serum or urine would be a good body fluid for monitoring chloramphenicol residues in tissues, whereas stomach content might be used as an indicator for chloramphenicol treatment for many days after therapy with t
