Eat A Cranberry Day – November 23, 2026

History of Eat A Cranberry Day

Cranberries have been around for tens of thousands of years; their origination is rooted in natural and geographical occurrences. Long ago, glaciers that receded after the Ice Age left behind cavities that eventually evolved into cranberry bogs, and other geological changes made the perfect environment for cranberries to grow in. 

The American Indians used and consumed cranberries, or ‘sassamanash’ as they called it, in numerous forms. They ate it, made dyes with it, and used it as a natural healer for war wounds. With its abundant health benefits, the Indians made their version of a cranberry energy bar known as ‘pemmican.’ Europeans who arrived in the 16th and 17th centuries were no strangers to these berries as they had their own cranberry bogs in parts of southern England. While the fruit has had many names, ‘craneberry’ was the most widely used because its flower was believed to be shaped like a crane. 

Wide-scale cranberry cultivation began in 1816 when Captain Henry Hall realized the positive impact of sand on his cranberry bogs. He developed a technique to spread sand over his cranberry vines, taking the cultivation world by storm. The technique spread and cranberry cultivation saw a rapid increase. The cranberry industry continued to grow over the years, leading to the innovation of new tools and techniques to make cultivation and harvesting more efficient. This generated thousands of job opportunities, and cranberries eventually became an indispensable part of the economy. Even global demand was on a steady increase.

The first case of pesticide contamination in the U.S. involved cranberries — the “Great Cranberry Scare of 1959.” Beginning in the mid-1950s, cranberry farmers introduced a new chemical called ‘aminotriazole,’ a known carcinogen, to control weeds in their bogs. The FDA approved the herbicide on the condition that it was applied after the harvest to ensure it doesn’t contaminate the berries. In 1958, the Delaney Clause prohibited the sale of foods containing cancer-causing substances, which led to compulsory tests showing aminotriazole contamination in some cranberries from Washington and Oregon. Just before Thanksgiving, Secretary of the Department of Health, Education and Welfare Arthur Fleming made an announcement warning the public against cranberries. Thanks to these special berries, governments worldwide started prioritizing food safety from that day by regularly recalling contaminated foods.

Today, U.S. Farmers harvest approximately 40,000 acres of cranberries each year, and the industry continues to see more advancements. On November 23, Eat A Cranberry Day is celebrated nationwide to pay tribute to these wonderful berries. There is no public record of the origin of this unofficial holiday and no congressional or presidential declarations to make it a national day. The earliest mention of Eat A Cranberry Day on the internet was in 2015.
