Coxsackievirus A21 permit; chemical assessments

Summary#

This Canada Gazette (Part I, published October 17, 2020) lists several Environment notices. It includes a ministerial condition that allows limited manufacture or import of Coxsackievirus A21, Kuykendall strain under strict containment, and updated screening assessments that would likely lead to adding some chemicals (including melamine, TCPP, and TDCPP) to the list of substances of concern under the Canadian Environmental Protection Act, 1999.

What it does#

• Ministerial condition for the virus:

  • Permits the manufacture or import of Coxsackievirus A21, Kuykendall strain for the notifier who filed information on August 4, 2020, but only under detailed conditions.
  • Requires work inside a contained facility at the appropriate containment level (the notice cites Risk Group 2 as the containment baseline).
  • Prohibits release outside the facility, mandates surface and liquid decontamination, autoclaving or incineration of waste, and written transfer/receipt rules.
  • Requires record keeping at the notifier’s principal place of business in Canada for 5 years.
  • These conditions came into force on October 2, 2020 and do not apply if the notifier already holds a licence under the Human Pathogens and Toxins Act.

• Chemical screening assessments and proposed actions:

  • Melamine — Updated draft screening concludes there may be a human health concern (mainly from foam products) and proposes recommending it be added to Schedule 1 of CEPA. The notice notes reported imports in 2011 of 10 to 100 million kilograms.
  • p‑Toluenesulfonic acid (PTSA) — Draft screening proposes it does not meet CEPA criteria; ministers propose no further action now. Reported imports in 2011 were 141,600 kg.
  • Triarylmethanes group (six dyes/pigments) — Final decisions:
    • Basic Violet 3, Malachite Green, Basic Violet 4, and Basic Blue 7 were concluded to meet one or more CEPA criteria; the ministers propose adding them to Schedule 1 and released a proposed risk-management approach.
    • Pigment Blue 61 and Brilliant Blue FCF were concluded not to meet CEPA criteria; no further action at this time for those two.
    • The group was reported imported in amounts of 1,000 to 100,000 kg each; Brilliant Blue FCF was also manufactured in Canada in amounts of 100 to 1,000 kg.
  • TCPP and TDCPP (flame retardants) — Updated draft screening proposes both meet CEPA criteria for human-health concern, largely because exposure from foam-containing products may be problematic; ministers propose adding them to Schedule 1 and released risk-management scope documents.
    • Reported 2011 import ranges: TCPP: 1,000,000 to 10,000,000 kg; TDCPP: 100,000 to 1,000,000 kg.
    • Both are proposed to meet persistence criteria but not bioaccumulation criteria.

• Public comment windows:

  • For the proposed chemical decisions, the notices give the public 60 days from publication to submit written comments.

Who's affected#

• Laboratories, researchers, biotechnology companies, and any organization that imports or manufactures Coxsackievirus A21, Kuykendall strain — they must follow the containment, disposal and record rules or hold a separate licence.
• Manufacturers, importers, formulators, and distributors of products containing melamine, TCPP, TDCPP, and the named triarylmethane dyes — these businesses could face future controls, reporting needs, or restrictions.
• Furniture, mattress, textile and foam-product makers and retailers — some notices single out foam-containing products (mattresses, upholstered furniture) as potential sources of exposure.
• Consumers — especially parents and caregivers of infants and young children who use foam mattresses or furniture, and people using products such as hair dyes or certain cosmetics — because some findings focus on exposure risks for infants and young people.
• Waste handlers and incineration/landfill operators — the notices set disposal expectations for contaminated materials and wastes.
• The public and stakeholders who may wish to comment during the 60-day consultation windows.

Why it matters#

• Worker and lab safety: the ministerial condition sets a clear set of rules for handling a live virus, covering containment, cleaning and waste handling to reduce the risk of accidental release.
• Potential regulations ahead: proposed additions of substances to Schedule 1 can lead to future rules that restrict or control how chemicals are used, imported, sold, or disposed of. That can mean product reformulation, supply changes, or new compliance costs.
• Consumer exposure concerns: the assessments highlight that foam-containing products can be a route of exposure for certain chemicals. The notices flag possible risks for infants and young children, which could influence product safety decisions by parents and manufacturers.
• Your chance to weigh in: the public has an opportunity to comment (usually 60 days) on the scientific conclusions and proposed actions before final decisions are made.
