Memorandum 25

Submission from the British High Commission, Canada

EXECUTIVE SUMMARY

  The Public Health Agency of Canada classifies pathogens using a risk system based on pathogenicity and mode of transmission. Recently there has been a shift towards classification using minimal containment levels required to provide safe manipulation of pathogens. (Paragraphs 1-2)

  The agencies responsible for overseeing bio-security in research facilities in Canada are the Public Health Agency of Canada (PHAC) and the Canadian Food Inspection Agency (CFIA), while transportation of pathogens into Canada falls under the jurisdiction of Transport Canada. Dangerous pathogens require permits from the Public Health Agency of Canada, Transport Canada and the Canadian Food Inspection Agency for their use in research facilities. In addition, laboratory facilities handling dangerous pathogens require prior certification from PHAC and where applicable, CFIA. (Paragraphs 3-9 and 15)

  The Public Health Agency of Canada publishes a manual with guidelines to follow for the design, construction, maintenance and protocols to be used in containment laboratories. This provides a set of general recommendations for facilities to follow when developing their own protocols and procedures. In the case of university laboratories, a bio-safety committee is appointed by the university to deal with all matters related to laboratory bio-safety and bio-security. (Paragraphs 10 and 19)

  All facilities dealing with dangerous pathogens are required to have inventory controls and emergency plans in place as part of their operational protocols, however there is no universal or standard procedure available to account for missing pathogenic material. Facilities are responsible for devising their own methods for inventory control and emergency preparedness. These activities are strongly encouraged by the Public Health Agency of Canada as well as public funding agencies. (Paragraphs 16-19)

INQUIRY INTO BIOSECURITY IN RESEARCH LABORATORIES, CANADA

By what mechanism(s) are micro-organisms classified with regards to their potential danger and their need to be contained?

  1.  The Public Health Agency of Canada classifies micro-organisms based on a risk level system that depends on pathogenicity, mode of transmission, availability of preventive measures and treatments, and severity of economic or health consequences brought about by a potential wide-spread infection. Recently there has been a shift towards classification of pathogens based on their handling requirements using four biological containment levels.

What are the categories of biological containment in use?

  2.  There are four progressively stringent containment levels in use, depending on the type of agents handled and based on the minimum containment level required for safe manipulation of pathogens. These containment levels indicate the operational, physical, engineering and technical constraints required for safe handling of pathogens. These procedures are in turn based on the pathogenicity, potential for serious health and economic consequences, and preventive measures and treatments available for particular pathogens. http://www.phac-aspc.gc.ca/ols-bsl/containment/index.html

How are licenses to use dangerous pathogens in research awarded?

  3.  Dangerous pathogens require importation permits depending on their source and the containment level required for their manipulation. The import and use of human pathogens is regulated by the Human Pathogens Importation Regulations and requires a permit issued by the Office of Laboratory Security at the Public Health Agency of Canada.

  4.  Human pathogens requiring containment levels 2, 3 and 4 require a valid permit. These permits allow for the import, use and storage of dangerous pathogens. Before issuing a permit, the Public Health Agency of Canada will inspect the research laboratory to ensure that criteria for containment level is adequate and that operational, mechanical and physical bio-safety and bio-security attributes are in place to handle pathogens at the specified containment level. After evaluation of the permit application and inspection of laboratory facilities, a permit is issued for single or multiple entries of the pathogen into Canada, on a case by case basis. http://www.phac-aspc.gc.ca/ols-bsl/pathogen/index.html

  5.  Permits for animal and plant pathogens are awarded by the Canadian Food Inspection Agency. In the case of zoonotic pathogens which can be transmitted from animals to humans, two separate permits are required, one from the Public Health Agency of Canada and another one from Canadian Food Inspection Agency. Both agencies will be involved in the inspection and certification of the laboratory facilities in this case.

What is the inspection regime for laboratories licensed to use dangerous pathogens?

  6.  Facilities for containment levels 3 and 4 require certification from the Public Health Agency of Canada for handling dangerous pathogens. There are approximately 90 containment level-3 laboratories and a single level-4 facility in Canada.

  7.  In order to initially certify containment level 3 and 4 facilities, the Public Health Agency of Canada will inspect the research laboratories to ensure that criteria for containment level is adequate and that operational, mechanical and physical attributes are in place for handling the pathogenic material. Guidelines to prepare for these inspections are provided by the Public Health Agency of Canada.

  8.  Furthermore, level-4 facilities undergo a yearly inspection to ensure that bio-safety attributes are maintained and updated. Level-3 facilities do not undergo further inspection after the initial certification, however in order to maintain their certification they are required to submit a form documenting any changes undergone in the facility after the initial certification on a yearly basis.

  9.  Finally, if zoonotic pathogens are concerned, the Canadian Food Inspection Agency is also involved in the initial inspection for certification of level-3 facilities.

What training is mandatory/recommended for staff working in containment facilities?

  10.  Guidelines for training staff in all containment facilities is provided by the document Laboratory Bio-safety Guidelines published by the Public Health Agency of Canada. This document is sent to facilities upon request or can be accessed through the agency's web-site.

  11.  Training is mandatory for certification of level-3 and 4 facilities, as it is evaluated as part of the Standard Operating Procedures for certification of these facilities. Training on potential hazards, reducing infection risks, operational procedures, decontamination and emergency protocols are recommended for containment level 2 to 4 laboratories. In addition, requirements for training staff in the physical operation and design of the facility are required for containment levels 3 and 4.

  12.  There are no standard training programmes outlined, however the Public Health Agency of Canada requires evidence that the training undertook is specific to the pathogens handled and that staff have completed and understood the training programme.

  13.  An instructional DVD on operational procedures for containment level-3 laboratories is available at a moderate cost from the Public Health Agency of Canada.

  14.  The Public Health Agency of Canada will be holding its second annual Canadian Bio-safety Symposium on 1-3 June this year. http://www.phac-aspc.gc.ca/ols-bsl/l3-n3-2003/index.html

What are the regulations regarding the storage and transportation of dangerous pathogens?

  15.  Regulations for storage and transportation of dangerous pathogens are under the authority of Transport Canada. Transport Canada regulations require an additional permit for transport and storage of dangerous pathogens under the category of Infectious Substances and Biological Products in the Transportation of Dangerous Goods Act. Compliance with these regulations involves following containment specifications and providing Transport Canada with information on staff training and storage or disposal procedures. http://www.tc.gc.ca/acts-regulations/general/t/tdg/regulations/tdg001/part—1.htm

What measures are in place to be implemented when pathogenic material cannot be accounted for?

  16.  Measures to account for missing pathogenic material fall under the responsibility of the facility. However, as part of the certification criteria for level-3 and 4 laboratories, a plan to control accidents involving dangerous pathogenic material and an inventory of the pathogens in the facility must be included in the Standard Operating Procedures submitted to the Public Health Agency of Canada. However currently there is no standard protocol in place for maintenance of inventories or emergency preparedness plans for laboratories to follow. Facilities are encouraged to report incidents to the local law authorities.

  17.  However, in case of highly infectious substances belonging to risk groups 3 and 4[31] the Public Health Agency of Canada must be informed if shipments of pathogens go missing or are delayed during their importation into Canada or while they are being transported from one facility to another within Canada.

  18.  Further control and compliance over incidents involving pathogenic material is indirectly exerted by funding agencies and provincial governments, which require that facilities be compliant with the guidelines indicated in the Guidelines for Laboratory Bio-safety produced by the Public Health Agency of Canada to authorise funding.

Who is responsible for overseeing security clearance for research students working with dangerous pathogens—what is the role of universities in this process?

  19.  Each university designates a bio-safety committee, which is responsible for overseeing security clearance requirements for students working with dangerous pathogens. All containment level-3 laboratories require all staff, from support to research staff working within the facility to undergo security clearances.
