A live opossum captured at Honolulu Harbor is the latest in a widening series of stowaway detections that is testing Hawaiʻi’s defenses against invasive animals. Employees at a freight facility spotted the animal on September 19 and alerted the Department of Agriculture and Biosecurity, whose inspectors trapped it the next day, according to the state’s [release](https://governor.hawaii.gov/newsroom/opossum-caught-at-honolulu-harbor/?ref=theamericanquorum.com).

Inspectors baited traps with cat food and apples, searched the surrounding area and reported finding no other opossums. The animal was euthanized under health protocols, and a tissue sample is being sent to the mainland for rabies testing. That step matters because Hawaiʻi remains the only U.S. state free of rabies, a status maintained through animal-entry controls administered by the state’s [quarantine branch](https://dab.hawaii.gov/ai/aqs/?ref=theamericanquorum.com).

## A pattern at cargo gateways

The Honolulu capture was not an isolated event. The department’s chronology lists another opossum caught near Hilo Harbor in August and one found in a container near Daniel K. Inouye International Airport in May. It also records four captures during 2025 and three during 2024\. Most were found at harbors, freight companies, warehouses or large retailers—locations consistent with animals hiding in containers, vehicles or other cargo.

That pattern underscores the limits of inspection at a state that depends heavily on imported goods. Plant Quarantine Branch manager Jonathan Ho told [SFGATE](https://www.sfgate.com/hawaii/article/hawaii-opossum-invasive-species-20039122.php?ref=theamericanquorum.com) that the agency can inspect regulated agricultural shipments and certain animal imports, but those categories represent about 10% of the 4,000 to 5,000 containers arriving in Hawaiʻi each week. General cargo such as vehicles, machinery and household goods may also carry animals but is not routinely inspected under the same authority.

## Ecological and public-health stakes

Opossums are not native to Hawaiʻi and are illegal to possess. If one escaped detection and established a population, it could prey on native birds, snails and invertebrates in an ecosystem with few comparable land predators. Ho described that risk as potentially catastrophic because Hawaiʻi holds unusually high numbers of endangered species and invests heavily in protecting native forests.

The rabies test addresses a separate public-health concern. Hawaiʻi’s official [program](https://dab.hawaii.gov/ai/aqs/?ref=theamericanquorum.com) says the state has never recorded an indigenous rabies case and has regulated arriving dogs, cats and other carnivores since 1912\. The latest opossum does not mean rabies has entered the state; the test is a precaution intended to preserve that record.

The department has also begun publishing a [dashboard](https://governor.hawaii.gov/newsroom/dab-news-release-on-biosecurity-dashboard/?ref=theamericanquorum.com) covering selected biosecurity work and directs residents to report suspected invasive species through the statewide 643-PEST hotline. The repeated opossum captures show why freight workers and the public are part of the detection system: inspectors can respond quickly once an animal is reported, but the sheer volume and diversity of arriving cargo leave gaps that surveillance alone cannot eliminate.
