Is LinkedList thread-safe when I'm accessing it with offer and poll exclusively?

I have a linked list samples:

protected LinkedList<RawDataset> samples = new LinkedList<RawDataset>();

I'm appending elements to the list in thread 1 like this:

this.samples.offer(data);

And I'm retrieving elements from it in a second thread like so:

public RawDataset retrieveSample() {
    return this.samples.poll();
}

Would this be considered as thread-safe? Even though thread 1 and 2 are both modifying the list they only do so on either the head or the tail of the list exclusively, right?

If it isn't can anyone point me to a class in the Java API that comes with poll/offer and is sure to be thread-safe?

Thank you in advance.

BTW: Collections.synchronizedList(new LinkedList()) won't give me access to offer/poll.
