Luckily for coffee sellers in California, state officials rejected a ruling that coffee shops must warn drinkers about a cancer-causing chemical in their brews.

California’s Proposition 65 requires sellers to inform customers about chemicals known to cause cancer, birth defects or reproductive problems. Coffee contains acrylamide, which has been shown to cause cancer in mice when given concentrated doses, so, in March, a court ordered that coffee companies must add a cancer warning label.
