McDonald’s in Japan has said it is having to ration the portions of fries it serves to customers because of a long running industrial dispute at ports on the West Coast of the United States.
There have been delays in containers being shipped from 29 ports since October.
Now the fast-food chain – which has 3,100 outlets in Japan – has said it risks running out of fries by the end of the year without the rationing.
To address the shortage it is importing more than 1,000 tonnes of frozen fries by air, some of which have already arrived there.
An additional 1,600 tonnes are being sent by sea from US East Coast ports. Those shipments are due to arrive in late January.
Japan is the biggest Asian market for US-made frozen potato products, importing $336 million (268 million euros) worth last year.
A US Potato Board official said last week that the port jams have at least doubled transit times for shipments of french fries to Japan from two to four weeks.
