Strategies for Next Steps

• Identify the number of these compounds  that should be present in a method for raw  milk using the criterion that the drug must  be approved for use in dairy production • Identify the number of these compounds  that should be present in a tissue method  using the criterion that they should be  approved for livestock and poultry and egg  production
