Important information for Established Dairy Farms
in accordance with the Grade "A" Milk Law of 2001

(The links below require Adobe's free Acrobat Reader to view.)

• One of the primary concerns of the law is with antibiotic contamination of milk.  Information on this may be found in manual DY-323
  
  
• Milk from farm bulk tanks must be picked up within 72 hours.  Tanks must be emptied at each pickup unless: the tank is emptied later and before the next milking or the bulk tank has a recording thermometer.  In all cases, bulk tanks must be washed once each 72 hours of use.
  
  
• If an established licensed dairy farm wishes to make changes to its milking system, it should consult the Equipment Installation Manual for requirements.  (This manual is primarily a table of contents with links to other documents found within).
  Here are some construction plan tips.
  
  
• Manual DY-348 provides information behind the setup of a new dairy farm to the owner of an established dairy farm for review.  This would be helpful in implementing changes on the established farm.
  
  
• If an established farm makes any changes to a well or water system, that farm must contact the Lansing Office at 800-292-3939 for a review of the planned changes and information on who to contact for approval of new well sites.
  
  
• Producers interested in direct loading of milk should consider how their milk will be sampled before shipment.  There are a variety of sampling methods, but all samples must be taken by a licensed sampler.  For further information consult your inspector and the following documents: DY-360 and DY-356
  
  
• For further information take a look at DY-321,  DY-344, DY-346.  These may or may not apply to your specific situation.
