The Chilean Agricultural Authority (SAG) has issued an urgent advisory following a surge in infestations of the Ecuadorian Moth (Thyrinteina arnobia) on vessels arriving from Ecuadorian ports and Guayaquil.
Authorities have confirmed that all vessels inspected recently have shown signs of contamination, prompting enhanced inspection and fumigation protocols.
Upon arrival, SAG inspectors are conducting daylight visual inspections of vessel decks, superstructures, hatch coamings, and accommodation areas. If egg masses or larvae are detected, Free Pratique is denied, and vessels must undergo fumigation by certified Chilean companies. This process results in delays of at least one full day and incurs costs estimated at USD 6,000 per vessel. Notably, fumigation carried out in Ecuador prior to departure is not recognised by SAG, meaning all vessels are subject to inspection regardless of prior treatment.
In response to the outbreak, SAG has introduced new documentation requirements for vessels arriving from Ecuador. Agents must submit a detailed list of containers loaded in Ecuador, including stowage positions, as well as information on Ecuadorian-origin containers loaded at other Pacific ports. A discharge list for Chilean ports must also be provided, along with a bay or stowage plan that clearly identifies Ecuadorian cargo. Colour coding is recommended to aid identification. Additionally, photographic evidence of container holds showing seals and container numbers is required. Although these measures primarily target containerised cargo, bulk and breakbulk vessels are equally subject to inspection and enforcement.
If traces of the moth are detected during inspection, the process is immediately halted. The vessel is denied reception, Free Pratique is withheld, and an immobilization order is issued. Fumigation of the vessel and any exposed cargo is then mandated before operations can proceed.
To minimise risk and avoid delays, vessels are strongly advised to conduct thorough self-inspections prior to arrival. Washing of decks, hatch covers, cranes, and superstructures with pressurised seawater is recommended. Particular attention should be paid to accommodation areas and hatch coamings. Hatches should remain sealed before departing Ecuador, and any visible insects or egg masses should be removed during transit. Crew members should be briefed and actively involved in preventive cleaning measures.
Chilean authorities emphasise that non-compliance may result in significant operational disruption. Vessel operators are urged to take immediate action to ensure readiness and compliance with SAG protocols.
