Flighted Spongy Moth Complex (FSMC) Season - 2026 Members with ships calling at certain Far East ports are reminded that between May and October, they will need to ensure their vessels are inspected and certified free from Flighted Spongy Moth Complex (FSMC) prior to departure. This measure is intended to minimise the risk of regulatory action upon arrival in countries where this pest is not native. The countries known to carry out seasonal pest inspection measures are: United States, Canada Australia, New Zealand, Chile and Argentina. US and Canada The Canadian Food Inspection Agency ( CFIA ) and the United States Department of Agriculture ( USDA ) issued a  joint FSMC bulletin  in February 2026, warning about the potential outbreak levels of this pest in 2026. In addition to obtaining FSMC-free certification, they recommend exercising extra vigilance during self-inspections. Vessels calling at North American ports should expect increased enforcement intensity in 2026, including closer scrutiny of self-inspection records and port-of-call histories. Vessels that are scheduled to call at the FSMC regulated areas during the specified risk periods, as outlined in the table below, need to be inspected and certified free of FSMC by a recognised certification body. The inspection should ideally be conducted during daylight hours and on the same day as departure.
