Fans of “Two-Buck Chuck” were hit with bad news two years ago when Trader Joe’s hiked up the price of its discount wine to $2.49. Now devotees of Charles Shaw and other affordable California wines are facing another unsettling announcement, but this one has implications for their health, not just their wallets.
A class action lawsuit was filed in March, claiming that some of the most popular low-priced California wines contain up to five times the maximum amount of arsenic that the Environmental Protection Agency (EPA) allows for drinking water. According to independent Denver laboratory BeverageGrades, almost a quarter of the 1,306 different types of wine tested contained arsenic levels greater than the EPA maximum.
Although there is no federal limit on the amount of arsenic permissible for foods and virtually no federal labeling requirements for wine, the EPA’s upper limit for arsenic levels in drinking water is 10 parts per billion. According to the lawsuit, the wineries “produce and market wines that contain dangerously high levels of inorganic arsenic, in some cases up to 500 percent or more than what is considered the maximum acceptable safe daily intake limit.”
What is arsenic?
Arsenic is a naturally occurring element in the earth’s crust that is more concentrated in certain types of rocks and minerals. Arsenic seeps into soil and water naturally as a result of erosion, but the majority of arsenic in the environment is the result of now-banned pesticides and animal feed additives.
The wine lawsuit refers specifically to “inorganic” arsenic, meaning the substance has been combined with other elements, increasing its toxicity. High doses of inorganic arsenic are known to cause serious health problems. Repeated or prolonged exposure can cause chronic arsenic toxicity, which can lead to cancer of the skin, bladder, liver, kidney, or prostate; diabetes; vascular or heart disease; nerve damage; and changes in skin pigmentation.
Which wines are high-risk?
According to BeverageGrades CEO Kevin Hicks, the price per liter seemed to correlate with the wine’s quantity of arsenic; the lower the price, the higher the amount. Many of the top offenders on the list are priced under $10 a bottle.
Brands with particularly high levels include Trader Joe’s Charles Shaw White Zinfandel (containing 3 times the limit the EPA set for drinking water), Ménage à Trois Moscato (4 times the limit), and Franzia White Grenache (5 times the limit). Sutter Home, Beringer, Fetzer, Flipflop, Cook’s, and Korbel were also among the 31 different brands bottled at 28 California wineries cited in the lawsuit.
What does this mean for me?
Although the Food and Drug Administration (FDA) has not issued an official recall or made a statement about the situation, some experts believe the potential exposure to such high levels of arsenic could be deadly over time.
Others, however, like a representative for The Wine Group, a company named in the lawsuit, claim it’s inaccurate and irresponsible to compare arsenic levels in wine to the maximum standard for water since most people drink far more water than wine on a regular basis. Additionally, the levels of arsenic cited in the lawsuit are being held specifically to American standards; the highest level of arsenic cited in the lawsuit (50 parts per billion) is only half Canada’s permissible limit of 100 parts per billion.
“We — and that includes the FDA — just don’t know enough about the levels of arsenic that should cause concern,” says One Medical’s Malcolm Thaler, MD. “Studies are underway, but until we know more, we should — for more reasons than just this — keep wine drinking within reason.”
