Collection Information

GENERAL - Label all containers with appropriate information - Animal ID, Owner Name, Veterinarian, Sample Type, Date.
REFRIGERATION - Refrigerate all samples until shipment.
MILK - Submit milk in a leak-proof container (i.e., plastic conical tube) with appropriate labeling. Follow pre-milking procedures, then direct a stream of milk into a sterile container, preferably held horizontally, to reduce the risk of drop-in contaminants. Samples may be collected from one or multiple teats (composite sample) from one animal.

Shipping Information

LEAKS - Ensure all samples are in leakproof packages and clearly labeled with Tissue Type/Animal ID/Owner Name. Include absorptive material to collect any leaks - double bag any fresh tissues.
PAPERWORK - Package paperwork separately in a waterproof, sealable plastic bag. Ensure paperwork is complete and specimens are labeled for easy matching. If you are using CF.755 Multiple Animal Continuation Form, please include a hard copy and email a copy to addl@purdue.edu.
MILK - Ensure the container is securely sealed and inside a leakproof plastic bag. If shipping different tissue types, clearly label each container with owner and animal ID (if applicable) and sample/tissue type. Ship specimens overnight with an ice pack. DO NOT SHIP OVER THE WEEKEND OR HOLIDAY.

Additional Information
National Mastitis Council guidelines for reporting are followed. Milk culture is used to diagnose a bacterial cause of mastitis. If 3 or more bacterial species are present, the result is reported as \\\\\\\\\\\\\\\"contaminated\\\\\\\\\\\\\\\" with a recommendation to re-sample. The ADDL does not perform any tests appropriate to assess the safety of raw milk for human consumption.
