EXAMINE ALL PRODUCT LABELS CAREFULLY!

The guidelines in this booklet may not be consistent with foreign regulations and laboratory methods.

Provision has been made for quantitative limits for certain substances. An official sample will only be called positive for these substances if the concentration of the substance is greater than the quantitative limit, and any other regulatory conditions are met. For example, see note B (below).

B. Penicillin G Procaine

Under certain conditions, quantitative analysis of a blood sample may be used as the basis for classification of a positive or negative with respect to procaine resulting from administration of penicillin G procaine products.

These conditions include:

  1. The last administration of a product containing penicillin G procaine, at a dose up to 6 million IU, occurs at least 48 hours before the scheduled post time of the race for which the horse is entered.
  2. The last administration of a product containing penicillin G procaine, at a dose up to 9 million IU, occurs at least 96 hours before the scheduled post time of the race for which the horse is entered. Dosages above 9 million IU may require a longer withdrawal than 96 hours.
  3. Approved procedures are established for notifying provincial officials and collection personnel.
  4. Approved procedures are established for collecting a blood sample.
  5. A statement is made and a blood sample is provided according to the provisions of section 170 of the Pari-Mutuel Betting Supervision Regulations.
  6. If all required conditions are met, a positive will not be classified for procaine unless the concentration in the blood sample is greater than 0.025µg/mL or 25ng/mL, as described in paragraph 3 of the Schedule.

    It is stressed that these results are presented as guidelines only and should not be construed as absolute for every horse to which this drug is administered. Agriculture and Agri-Food Canada is not responsible for results differing in any way from these results.
