Fact check: What are the largest documented seizures or busts of cocaine coming into the US?

1. Summary of the results

Based on the analyses provided, the largest documented cocaine seizure in U.S. history was the 39,525 pounds of cocaine seized at the Port of Philadelphia's Packer Marine Terminal in 2019, valued at $1.3 billion and representing the largest seizure in U.S. Customs and Border Protection's 230-year history ^[1].

Other significant seizures include:

• Coast Guard operations that offloaded 26.5 tons of cocaine in Port Everglades, worth an estimated $715 million, seized in international waters off the Eastern Pacific Ocean ^[2]
• A Colombian drug trafficking organization that smuggled at least 43,000 kilograms of cocaine onto commercial flights from Colombia to the US between 2016 and 2023 ^[3]
• DEA operations in the first half of 2025 that seized over 201,500 pounds of cocaine across multiple operations ^[4]

Additional notable seizures mentioned include 197 kg of cocaine worth $25 million at the Blue Water Bridge near Sarnia, Ontario ^[5], and 193 pounds of cocaine intercepted near the Ambassador Bridge ^[6].

2. Missing context/alternative viewpoints

The analyses reveal several important contextual elements not typically highlighted in discussions of large cocaine seizures:

• International vs. domestic seizures: Some of the largest operations involve international waters and cross-border cooperation, indicating that the drug trafficking problem extends far beyond U.S. borders ^{[2] [5]}
• Ongoing criminal enterprises: The Colombian trafficking organization case demonstrates that some of the "largest busts" represent multi-year operations rather than single seizures, with 43,000+ kilograms smuggled over seven years ^[3]
• Geographic distribution: Major seizures occur at various entry points including Philadelphia ports, Texas border crossings, Puerto Rico airports, and Canadian border crossings, showing the diverse routes used by traffickers ^{[1] [7] [8]}
• Operational scope: The 2025 DEA statistics show that large seizures are part of continuous, systematic enforcement efforts rather than isolated incidents ^[4]

3. Potential misinformation/bias in the original statement

The original question appears neutral and factual, seeking documented information about cocaine seizures. However, there are potential areas where incomplete information could lead to misunderstanding:

• Definitional ambiguity: The question doesn't distinguish between single-event seizures versus cumulative seizures from ongoing operations, which could lead to comparing different types of enforcement actions (p1_s1 vs. p3_s2)
• Geographic scope confusion: Some sources include seizures at Canadian border crossings and international waters, which may not technically qualify as "coming into the US" depending on interpretation ^{[5] [2]}
• Temporal context missing: Without specifying timeframes, the question could conflate historical record-breaking seizures with recent operational successes, potentially misrepresenting current enforcement effectiveness (p1_s1 vs. p1_s3)

The analyses suggest that law enforcement agencies and government officials benefit from publicizing large seizure numbers as they demonstrate operational success and justify continued funding for anti-drug operations.
