Ptacek's IGA in Prescott grilled and served up the bratwurst Saturday, the St. Paul (Minn.) Pioneer Press reported.
"It started as a meat market 100 years ago, so it made sense to incorporate meat into our celebration," said store owner Pat Ptacek. "I decided, what is the world-record brat?"
The brat was made in-house by Ptacek IGA employees, while the bun was made by Pan-O-Gold Baking Co., which makes brands such as Country Hearth and Village Hearth.
Jimmy Hanson, from Pan-O-Gold, estimated the bun cost about $20,000 to make.
"Sometimes, you've gotta do a feel-good, and one family's gotta take care of another," Hanson said. "Not everything's about making money."
At the event Saturday, the brat, along with an additional brat of nearly the same length, was sliced up and sold for $4 per serving.
Proceeds from the event, which also included beer, music, a petting zoo and other food and activities, were donated to Have a Heart Inc. of River Falls, Wis., an organization that offers a respite program for families and kids with developmental disabilities.
As for the record, a World Record Academy spokesman said Saturday that the organization was aware of the attempt and it would be an official record-breaker once all the paperwork and photographic evidence was submitted.
