Excess formaldehyde was extracted from embalmed animal cadavers by vascular perfusion or combined perfusion and percolation with 20% ethanol. The perfusion was undertaken through a carotid artery and the percolation through the serous body cavities for 1-2 h. Nineteen goats were perfused once and one goat and three cows were perfused and percolated twice a day for 3 days. The extracted cadavers were stored in 20% ethanol or in a freezer at -20 degrees C. The mean value of the atmospheric concentration of formaldehyde after extraction was 0.27 +/- 0.05 mg/m3 for goats and 0.39 +/- 0.12 mg/m3 for cows.
