This guidance document is for mollusc culturists who will:
- receive a declared wild or cultured mollusc harvested directly from the natural waterways of Canada for the purpose of culture;
- send declared cultured molluscs for the purpose of culture, processing commercial, release into natural waterways, and research.
A permit from the CFIA is required if wild or cultured molluscs are coming from an area with a different reportable aquatic animal disease status than the area where the culture facility is located.
A permit from the CFIA may be required for sending wild or cultured molluscs to an area with a different reportable aquatic animal disease status than the area where the culture facility is located.
For more information, please review the declarations.
Culturists have two options when bringing in or receiving a declared mollusc:
- Receive the animal with an unknown disease status into a biocontained culture facility or processing plant; or
- Send or receive healthy animals as long as:
- they come from a facility that has a preventive control plan that prevents the introduction of the diseases
- they have been inspected and tested by the CFIA;
- the test results are determined to be negative; and
- They are shipped in containers and water (including ice) that is free of the diseases.
Apply for a Movement Permit to a Closed Premises (CFIA/ACIA 5749) - PDF (154 kb) to receive wild molluscs that are harvested directly from the natural waterways of Canada, or to receive cultured molluscs and the disease status is unknown. To subsequently move the animals out of the biocontained facility, permission from the CFIA will be required.
Apply for a Movement Permit for Molluscs and Things (CFIA/ACIA 5758) – PDF (166 kb) if segregation, inspection and testing is required prior to shipping declared molluscs from your facility. If declared molluscs require segregation, inspection and testing before they are moved to your facility, you should request that their owner apply for the permit.
In addition to a possible CFIA permit, culturists may also require authorization to move molluscs by Fisheries and Oceans Canada (DFO) and/or the province or territory in which your facility is located. For more information, visit the Introductions and Transfers web site.
Please note that all molluscs harvested for human consumption are subject to the Canadian Shellfish Sanitation Program.
The period of time that the permit is valid is flexible, depending on the needs of the planned movement. Please indicate your movement needs on the application and discuss them with the CFIA inspector.
Culturists should follow the appropriate permit conditions for their specific needs:
- Permit Conditions to Receive Molluscs into a Biocontained Facility;
- Permit Conditions if Sending Molluscs from a Culture Facility that Requires Segregation, Inspection and Testing.

How to comply with the permit conditions
Before the CFIA issues a permit, a CFIA inspector will work with the applicant to verify that the facility can meet the permit conditions, and to verify ongoing compliance with the permit conditions during the time that the permit is valid. The CFIA may inspect documents and records, the physical layout of the facility, and how it operates in order to assess their ability to meet and ongoing compliance with the permit conditions.
The following are examples of ways to comply with permit conditions:
Preventive control plan for a biocontained facility
- You are required to demonstrate to the CFIA that disease will not spread if you are bringing potentially infected molluscs into a facility designed for biocontainment.
- Written documentation is required to show the physical, operational and decontamination measures employed that will mitigate the risk of disease spreading. You must address this risk for any animal, water, feed, fomites or vectors that will leave the facility, including the people that work or visit the facility.
- If disinfectant footbaths are employed, the CFIA will verify that measures are in place so that they do not contribute to spread of disease.
Inspection and sampling of molluscs
- Make an appointment with the CFIA veterinary inspector and provide inventory and location information of all the animals to be inspected and sampled.
- Provide assistance during the sampling process and provision of all equipment required to gain access to the animals for selection of samples by the CFIA. Expect that molluscs will be sampled from each holding unit (or a selection of them if there are many).
For more information on how to comply with these or other permit conditions, contact your CFIA Area Office.
Once a permit is issued, check if the declarations have changed for the origin and destination prior to each movement to ensure that the permit still applies to the planned movement. Please consider bookmarking the Declarations page for easy access.
General information related to movements
The permit and its conditions may be amended only by the Minister of Agriculture and Agri-Food or by an inspector who is designated for the purposes of the Health of Animals Act. The permit and its conditions may not be amended with respect to a specific movement after it has already occurred. If an amendment is required to a valid movement permit that has already been issued under this program, or if a change to permit conditions is desired, submit a new application and check the Amendment or Derogation box in Section A.
The permit holder must meet all of the conditions specified in documents attached to the permit, or else the movement of the animal or thing is not permitted. The permit holder is also required to notify the CFIA when they suspect or detect any reportable disease in an animal.
The CFIA may dispose of an animal or thing, or order that it be disposed of, when it:
- is suspected of being affected or contaminated by a disease or toxic substance;
- has been in contact with an animal or thing that is, or is suspected of being affected or contaminated by a disease or toxic substance; or
- is suspected of being a vector or the causative agent of a disease or a toxic substance.
The CFIA inspector may also order that that an animal or thing be treated if they consider that the treatment will effectively eliminate the disease or prevent it from spreading. Although compensation may be awarded in respect of disposal or treatment costs, the Government of Canada is not liable for any costs incurred by a person required to do anything under the legislation respecting the health of animals.
If a designated animal is moved into an area that either violates the conditions of the permit or contravenes the Health of Animals Act or Health of Animals Regulations, the CFIA may order the animal returned without delay to the area from which it was moved or to an area of equal or lesser health status.
Those who transport live aquatic animals by air should comply with the International Air Transport Association (IATA) Live Animals Regulations, approved by the World Organization for Animal Health (OIE). For all forms of transport, suitable arrangements must be made for water quality, ambient temperature, oxygenation and general care of the animal during transportation. An animal must be fit to be transported and should not suffer stress that renders them infirm, ill, injured or fatigued during the journey.
The permit and its conditions cover all persons who are moving the animal or thing on behalf of the permit holder. The permit holder remains responsible for the shipment's continued compliance with the conditions of the permit.
