Irish Butter is popular for its rich flavor and super creamy texture. These desirable qualities are usually attributed to the grass-fed cows it comes from.
Nutritionists say eating grass-fed butter may be healthier than regular American butter, helping to boost immunity, improve blood sugar, and improve heart and bone health.
The most popular brand of Irish butter in the United States right now is Kerrygold, which you’ll probably recognize by its eye-catching and shiny silver and gold packaging that really helps the product stand out on store shelves. The brand has become particularly sought after amid the butter coffee craze that the lifestyle guru Dave Asprey started in 2009.
If you notice Irish Kerrygold butter suddenly missing from your local supermarket, well, you can blame that same hard-to-miss packaging.
SFGate reports that Costco stores in California and New York recently ripped Kerrygold butter from shelves because its usual foil wrapper may violate new state rules prohibiting PFAS, or perfluoroalkyl and polyfluoroalkyl substances, in food packaging.
Both states recently enacted laws banning these so-called “chemicals forever,” which can pose risks to human health, according to the U.S. Environmental Protection Agency. Several other states are adopting similar rules this year, for Bloomberg Law.
A Kerrygold representative said SFGate that society”made the responsible decision to reformulate some of our packaging” in light of the new regulations, adding that butter will soon be returning to stores, with PFAS-free packaging.
Irish Center reported last month that Kerrygold had temporarily halted shipments to the United States “to ensure that no impacted products would be on the shelves by the time the new state regulations in New York and California take effect.”
A Costco official in San Francisco said SFGate the popular butter probably wouldn’t return for another month or two.
