Surgeon General Vivek Murthy’s call Friday to require alcohol labels warning of cancer risk will likely face strong resistance in Congress, which would have to pass a law to require the labels.

The alcohol industry fiercely opposes labeling as well as stricter guidance around consumption — the government currently recommends men consume no more than two drinks per day and women no more than one — and has cultivated support among lawmakers through an expensive lobbying and political operation.

The U.S. surgeon general said alcoholic beverages should carry cancer warnings to increase awareness that the drinks are a leading cause of preventable cancers.

An act of Congress would be required to change the existing warning labels on bottles of beer, wine and liquor. Today, federal rules require only a warning against drunken driving and drinking while pregnant, as well as a general warning that alcohol “may cause health problems.”

U.S. Surgeon General Vivek Murthy on Friday recommended that Congress act to put warning labels on alcohol products and put out a report linking drinking to seven different cancers.

Dr. Murthy’s report linked alcohol consumption to a higher chance of developing mouth, throat, esophagus, larynx, liver and colorectal cancers, as well as breast cancer in women.
