The National Geographic Sea Lion, a small expedition vessel operated by Lindblad Expeditions-National Geographic, has passed its most recent U.S. Centers for Disease Control and Prevention Vessel Sanitation Program inspection with a score of 86, the minimum threshold the CDC considers acceptable. Inspectors identified 42 deficiencies during the review, according to records posted in mid-August.
The score places the ship in a precarious position. The CDC's grading system runs from 0 to 100, with scores below 86 triggering increased oversight, potential sailing restrictions, or mandatory remediation before passengers board. While the National Geographic Sea Lion avoided those consequences, the thin margin leaves little room for error on future inspections.
The vessel operates small-group expeditions focusing on remote and environmentally sensitive destinations, often in Alaska and other pristine regions where fewer than 300 passengers travel per sailing. These cruises command premium pricing, sometimes exceeding several thousand dollars per person, and typically attract passengers interested in wildlife viewing and expert-led shore excursions rather than onboard amenities.
Cruise passengers booking passage on this or any other cruise ship can review CDC inspection scores and deficiency reports on the agency's official website. These records are public and updated regularly, offering transparency on sanitation standards across the industry. A single inspection score does not predict future performance, but passengers concerned about cleanliness standards may want to check the most recent results before booking or ask cruise lines about corrective actions taken after any inspection reveals issues.
