ABSTRACT
This study was designed to evaluate the effects of different storage conditions on total bacterial count (TBC) determinations made in goat bulk tank milk using an automated flow cytometry method. The storage conditions tested were storage temperature (refrigeration at 4 and 10°C or freezing at -20°C), the use of a preservative (no preservative, NP; azidiol, AZ; or bronopol, BR), and the age of the milk samples for each analytical condition (storage times at 4°C: from 0 h to 5 d for NP; and from 0 h to 22 d for AZ and BR; storage times at 10°C: from 24 h to 2 d for NP and from 24 h to 22 for AZ and BR; storage times at -20°C: from 24 h to 22 d for NP, AZ, and BR).
