Shipboard hygiene

Communicable-disease + gastroenteric-outbreak + potable-water hygiene management onboard — the routine practices that stop a single illness becoming a fleet-wide outbreak.

Why it matters

A single norovirus case on a cargo ship becomes a fleet-wide crew-change disruption in days; on a passenger ship it's an outbreak that closes voyages + triggers PSC + WHO IHR 2005 notification. Legionella outbreaks in ship potable-water systems have killed crew + passengers. Salmonella from raw-food handling has ended careers. The controls are unglamorous but the failure modes are severe.

Common hazards

• Cross-contamination in the galley (raw + cooked food + inadequate hand washing).
• Legionella in the potable-water system (stagnation, insufficient chlorination, low water temperature).
• Norovirus + gastroenteric spread via shared handles + surfaces + inadequate isolation of ill crew.
• Rodent + insect infestations in stores or accommodation.
• Inadequate cleaning of the messroom + heads + accommodation.
• Inadequate laundry temperature control (parasites + bacteria persist below 60°C).

Practical checklist

• Galley: separate boards + knives for raw + cooked; hand-wash station + hot-water at every prep station.
• Potable water: chlorination residual monitored + logged daily; monthly biological testing where possible.
• Ill-crew isolation: dedicated cabin + separate crockery + laundering procedure documented in the SMS.
• Accommodation cleaning: daily messroom + heads + hourly high-touch surface disinfection during outbreaks.
• Laundry: minimum 60°C wash cycle documented in the SMS.
• Pest control: monthly rodent + insect inspection; documented in the Deratting Record.
• MLC A3.2 galley + food-service inspections: monthly, signed by Master.

Mistakes to avoid

• Treating hygiene as a domestic task rather than a safety-critical control.
• Continuing an ill crew member on food-handling duty because "we're short-staffed".
• Skipping the Deratting Record because the vessel "doesn't have rats" — the record documents the check, not the presence.
