Did you receive a minor office-based surgical procedure at Dr. Lorin Harding’s clinic?

An infection prevention and control inspection by the College of Physicians and Surgeons of Ontario (CPSO), and investigation by City of Hamilton Public Health Services identified that patients who received in-office surgical procedures at Dr. Lorin Harding’s clinic in Hamilton may have been exposed to improperly cleaned instruments. Examples of the procedures would include removal of skin tags, warts, moles and cysts or biopsies of skin cancers. Read the June 28, 2017 IPAC report for Dr. Harding's clinics (PDF, 87 KB).

Improperly cleaned surgical instruments carry a risk of transmitting infectious diseases, such as hepatitis B, hepatitis C and to a lesser extent human immunodeficiency virus (HIV) to clients. Public Health Services has assessed the risk at Dr. Harding’s office as low.

Dr. Harding has offered these types of procedures from November 1979 to December 2005 at 399 Greenhill Ave, Hamilton and from December 2005 to June 8 2017 at 631 Queenston Road, Hamilton.

As a precaution, the City of Hamilton Public Health Services recommends that patients who received in-office surgical procedures performed by Dr. Harding to contact their primary care provider (family physician, nurse practitioner or walk-in clinic) to discuss testing for hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Please take this letter (PDF, 58 KB) which outlines the recommended testing to your primary care provider.
