McDonald's employees in 19 cities across the United States have filed complaints with the U.S. Occupational Safety and Health Administration (OSHA) over workplace-related concerns, BBC reports.
The 28 workers are claiming they were injured while on the job because of lax safety standards and faulty equipment. Some also claimed that they had been advised to treat their wounds with mayonnaise and mustard.
Company spokeswoman Heidi Barker Sa Shekhem assured government officials, investors and consumers that they are "committed to providing safe working conditions for employees in the 14,000 McDonald's Brand US restaurants," the site also reports.
McDonald's has also made headlines for recent administrative changes in light of unfavorable economic results.
The fast-food retailer's new Chief Executive Officer Steve Easterbrook is confronting worse-than-expected sales for the month of February.
The company has reported its ninth straight month of shrinking same-store sales, with the United States accounting for a four-percent decline, Bloomberg reports.
"This likely ups the urgency in terms of this new management team putting a plan out there to turn around the business," Stephens Inc. analyst Will Slabaugh told the site.
