A longtime McDonald's employee who reviewed food in TikTok videos has died at 100: The 'McFamily has lost an effervescent light'

• 100-year-old McDonald's employee Ruth Shuster died Sunday, The Pittsburgh Tribune-Review reported.
• She starred in numerous videos on a Pennsylvania McDonald's franchise's TikTok account.

A 100-year-old woman who appeared in numerous TikTok videos made by a Pennsylvania McDonald's franchise has died, the restaurant's owner confirmed to Insider.

Ruth Shuster died on Sunday and had worked at the McDonald's Big Mac Museum restaurant in North Huntingdon, Pennsylvania, for almost three decades, according to the local outlet The Pittsburgh Tribune-Review.

Michael Delligatti, the owner of the McDonald's Big Mac Museum restaurant, said in a statement emailed to Insider that the "McFamily has lost an effervescent light" and "Ruthie Shuster's sunny optimism brought joy to everyone who knew her."

Shuster was featured in multiple popular videos on a TikTok account for the Western Pennsylvania McDonald's franchise that owned the restaurant where she worked.

The TikTok account had a series called "Ruthie Reviews," where Shuster would sample various menu items — pull-apart donuts, a pumpkin pie, a "Thank You" meal designed for educators — and review the foods

One TikTok with the thumbnail caption "Meet Ruthie" says that she was a greeter at her McDonald's, and "loves dancing, singing, smiling, and working at McDonald's." Clips starring Ruthie garnered in total over 800,000 views on TikTok.

Shuster was born in North Huntingdon and was the child of Italian immigrant parents, the Pittsburgh Tribune-Review reported. She worked a variety of jobs through her life, including as a seamstress and at a gift store, according to report.

A sign outside her McDonald's location now says, "Rest in peace, Ruthie. Thank you for the sunshine!," according to KDKA 2, the CBS-affiliate in Pittsburgh.

For her 100th birthday last year, Shuster's McDonald's location gave her the honor of "Queen for a Day" and a red robe to wear, and a bobble head was made after her image and placed in a display case, according to The Pittsburgh Tribune-Review.
