How to correctly inherit thread culture in a parallel block?

I'm using automatic globalization on an ASP MVC website. It works fine until it reached a parallel block:

public ActionResult Index() 
{
     // Thread.CurrentThread.CurrentCulture is automatically set to "fr-FR"
     // according to the requested "Accept-Language" header

     Parallel.Foreach(ids, id => {
        // Not every thread in this block has the correct culture. 
        // Some of them still have the default culture "en-GB"
     }) ; 

     return View()
}

What is the best way to make the parallel block inherit the culture? apart from this solution:

public ActionResult Index() 
{
     var currentCulture = Thread.CurrentThread.CurrentCulture  ;

     Parallel.Foreach(ids, id => {
         // I don't know if it's threadsafe or not. 
         Thread.CurrentThread.CurrentCulture = currentCulture ; 

     }) ; 

     return View()
}
