More than 3,500 asylum seekers at the French port have tried to enter the UK through the Channel Tunnel this week, and Prime Minister David Cameron said that the crisis was likely to last for the rest of the summer.
The unrest has caused chaos for traffic across the Channel, with reported tailbacks of 6,000 lorries in Kent.
Jersey’s Customs and Immigration Service are now maintaining regular contact with their French counterparts over the crisis.
‘We are fully alert to it,’ said Andy Hunt, an assistant director at Customs.
‘We are in regular contact with our colleagues in St Malo and are keeping an eye on whether the problem is moving west from Calais, but there’s no indication at the moment that it is.’
Mr Hunt added that any asylum seekers who come to Jersey via the European Union would be returned to France because of an agreement between the two jurisdictions.
Condor Ferries have reported a 6% increase in passenger traffic from France to the UK compared to the same time last year.
A spokesman said some of the increase was believed to be because of the Calais disruption.
There are about 5,000 asylum seekers in Calais, most of whom are living in a makeshift camp.
Their numbers have almost quadrupled over the last year.
The majority of the migrants come from countries where there is unrest or civil war, including Somalia, Sudan, Eritrea and Syria.
An extra 120 French police officers have been sent to Calais to help bring order to the crisis, while British Home Secretary Theresa May has pressed for the installation of £7 million of UK-funded fencing around the rail terminal in France.
The Ministry of Defence has also announced that it will be intervening by turning army barracks into temporary lorry parks to help relieve traffic congestion in England.
