Your MN Beer Might Have Tiny Pieces Of Plastic In It
Craft beers are delicious, but a recent study conducted by the University of Minnesota shows that craft beers brewed with water from the Great Lakes including Lake Superior contained trace levels of microplastic!
None of the beers tested were named in the study, but there are A LOT of craft brewers that dot the shores of Lake Superior. In the study researchers tested the composition of 12 beers made using water from the five Great Lakes which included three from Lake Superior.
Seven brands of beer were bought from liquor stores in Minneapolis, two were growlers purchased in Duluth, and the other three were picked up in Michigan and New York.
All 12 beers contained microplastics, which are defined as plastic particles of 0.1-5mm in length in the study. The 12 beers averaged about 4 pieces of microplastic per liter, meaning someone drinking the beverages would consume around 520 particles every year if they drank just a beer a day.
If there is good news to come out of this study it is that two out of three beers containing Lake Superior water were below the average. The average was inflated by a significant amount of microplastic found in a single beer from Lake Michigan. GROSS.
Beer isn't alone in this issue of microplastics as the Guardian reports drinking water supplies in 12 countries were found to have 83 percent of it polluted with microplastics, with America the highest with 94 percent.
