S ummary : Various micro‐organisms were exposed to methyl bromide (MeBr) gas at concentrations of 20–40 mg/l for 20 h at 25°. A significant reduction was obtained in the number of viable bacteria and Aspergillus fumigatus spores, both in the dry form and in semifluid faeces, but no reduction was detected either in dried Bacillus subtilis spores or in one of the bacteriophages tested. The investigation indicates that MeBr is less effective against certain viruses, bacteria and fungi than against coccidial oocysts. The results suggest that fumigation of commercial poultry houses with these concentrations of MeBr may not, in all circumstances, provide the overall reduction of poultry pathogens desired.
