International health

International health controls are in place to prevent the spread of infectious disease into Britain fro: 

  • vessels
  • seafarers
  • passengers

Over 150 vessels are boarded annually by officials of the Cornwall Port Health Authority to understand the health status on board.  Particular attention is given to ships arriving from infected areas where diseases such as yellow fever, cholera and plague are prevalent.  

Countries that become infected are required under International Regulations to notify the World Health Organisation (WHO). This must be done within 24 hours of them becoming aware of the first case of such disease. Port Health Authorities receive a weekly update on the disease situation within infected countries. This regime of surveillance and control forms the first barrier to the international spread of infectious disease through shipping.

Legislation and notification of illness

The principal legislation that involves ships and aircraft arriving from outside the UK are the

  • Public Health (Ships) Regulations 1979 (as amended) 
  • Public Health (Aircraft) Regulations 1979.

Both these sets of Regulations reflect the provisions of International Health Regulations 2005.

These regulations require that port health is notified of any cases or symptoms of infectious disease aboard an aircraft or vessel before it arrives in port.

Arrangements will be made for a medical officer to visit the ship, assess the patient and initiate controls to stop disease being introduced into the UK.

Cruise liners

The situation is slightly different for cruise liners. The majority of infectious disease control work relates to suspected and confirmed cases of food poisoning resulting from the consumption of food contaminated with bacteria such as

  • Salmonella
  • Campylobacter
  • E. coli
  • Staphylococcus
  • food contaminated by banned food additives and toxic chemicals

There are also controls over conditions aboard vessels aimed at preventing public health hazards for crew and passengers.

Ship Sanitation Control Exemption Certificate

The International Health Regulations 2005 require that ships must have a valid Ship Sanitation Control Exemption Certificate.

This is renewed every six months.  Inspections must be carried out at a designated port.   

The ports designated to carry out such inspections and issue the required certification are:

  • Falmouth
  • Penryn
  • Truro
  • Fowey
  • Penzance

There is a charge for the inspection.

  • are properly managed
  • free from pests and disease
  • and that food is stored and prepared hygienically

Water supplies to ships and aboard vessels are also monitored.  In circumstances which pose an imminent risk to health, port health will work with the Maritime and Coastguard Agency to detain the ship until remedial measures have been taken.
