The country’s food agency warned against using evergreens in food after the city of Ghent suggested an unusual form of recycling: spruce needle butter.

A day after Belgium warned against eating Christmas trees, Swedish officials said that the needles can be safely used to make butter and other products -- as long as the trees are young and wild.

Belgium’s Federal Food Agency on Tuesday warned people to not eat their Christmas trees after a city council suggested recipes to reuse conifers following the holiday season. The agency was forced to issue the bizarre warning after the council in Ghent City launched a campaign last Thursday encouraging people to recycle their Christmas trees to reduce waste.

In a surprising twist to holiday traditions, Belgians are encouraged to eat their Christmas trees to combat waste. However, the Federal Food Agency quickly intervened, warning against this unusual practice due to safety concerns over pesticides and chemicals used in tree cultivation.
