The first step in bulk tank culturing is obtaining a good sample.  Then, the sample needs to be stored correctly and transported rapidly to the laboratory for culturing.

• Agitate the bulk tank for at least 5 minutes to ensure the milk is well mixed.
• Collect the milk from the top of the tank using a sterile dipper.  Do not sample through the spigot or use a contaminated dipper or cup to collect the milk.  Use the milking gloves provided to collect a sterile sample.
• Collect one sample daily over 3 to 5 days and freeze the sample as soon as possible.
• Send the frozen samples to the laboratory in the pre-paid mailer early in the week.
