The State of Iowa Alcoholic Beverages Division recently released a new warning about a not even that hidden potential threat to the health when out drinking. Authorities pointed out that copper cocktail mugs that have recently come back in fashion might also bring along food poisoning.
This comes besides the usual problems tied to having one too many drinks and an increased alcohol consumption.
Copper Cocktail Mugs Are Commonly Associated with the Moscow Mule
Copper mugs were commonly used when serving the Moscow Mule or the old Whisky Sour, but at least for a while, they stopped being as often utilized. As the latest trends in the mixology world are not only what you serve, but also in what you receive a drink, the mugs are once again back in the limelight.
The Alcoholic Beverages Division warned that the because of their copper alloy material, such mugs could bring food poisoning with them. Copper alloys and copper in itself are poisonous when consumed. The US State Department declares that copper is prohibited from coming into contact with any food or liquid that has a pH level below 6.0. It offers fruit juice, wine, or vinegar, as examples.
The Moscow Mule cocktail, which is served in copper, has a pH level well below this value. However, another important element is the interior coating of the vessel itself. Namely, not even this cocktail should be consumed from a mug with a copper coating.
Still, copper mugs coated with stainless steel or nickel, are recommended for use instead. The statement explains that “High concentrations of copper are poisonous and have caused foodborne illness. When copper and copper alloy surfaces contact acidic foods, copper may be leached into the food.”
The same warning includes some of the symptoms of a possible copper poisoning. These include stomach pains, vomiting, drowsiness, fainting fits, and confusion. Cooking in uncoated copper cookware can also result in acidic foods that might also lead to copper toxicity, which is sometimes referred to as copperiedus or hypercupremia.
