Controlling on-farm inventories of bulk-tank raw milk--an opportunity to protect public health.

Hazard Analysis Critical Control Point programs provide a systematic approach for the reduction of food safety problems through preventive measures. On-farm programs similar to Hazard Analysis Critical Control Point, which target pathogen reduction and screening can provide assurance to processors and consumers that on-farm food safety is a high priority. Additional voluntary oversight of farm practices, including monitoring of and controlled access to raw milk supplies on the farm could further contribute to public food safety. Off-farm sales of raw milk directly to the public have resulted in foodborne outbreaks of multidrug resistant salmonellosis in California and Washington when raw milk was used for unlicensed cheese production. If dairy producers in those cases had voluntary programs in place to inventory, monitor, and control access to raw milk supplies, the outbreaks probably could have been prevented.
