Red Bull is shipping its own food to the Japanese grand prix this weekend.
It is in the country, ravaged by the earthquake, tsunami and nuclear crisis earlier this year, that Sebastian Vettel will likely wrap up his 2011 title.
Due to the concerns about radioactivity, Red Bull has modified its usual routine for the preparation of food for the 80-person race team, reports Bild am Sonntag newspaper.
Usually, perishables like meat, fruit and vegetables are bought locally, but for the Suzuka round Red Bull - and presumably other teams - are taking these items from Europe.
The report said team boss Christian Horner has also told his staff not to eat out this weekend.
Last weekend, the MotoGP world raced at Motegi, located just 130 kilometres from the Fukushima nuclear plant.
Spanish rider Jorge Lorenzo revealed he used soap and bottled water to wash himself rather than take showers, and Dani Pedrosa said he is throwing away his clothes rather than taking them home to Europe.
As for F1, Toro Rosso driver Jaime Alguersuari told Marca newspaper: "I think the situation is totally calm and we are very far from Fukushima.
"I am coming without any fear."
