Kaylie Santos, a 22-year-old former night manager at a Southbridge, Massachusetts McDonald’s, was charged with distributing food with a harmful substance on May 18, 2026. Police allege Santos contaminated french fries by spitting into a carton and eating some before serving them to her ex-girlfriend via a drive-thru window.
The charges against Santos follow the circulation of a viral video that surfaced last week, which allegedly showed the manager tampering with food intended for a customer. According to court records, the incident occurred on April 9, and the evidence was captured both by restaurant surveillance and a private Snapchat story posted by Santos.
Surveillance Evidence and Criminal Charges
Southbridge police reports indicate that surveillance footage from the McDonald’s location shows Santos, who served as a night manager, spitting into a fry carton. The footage allegedly captures her shoving fries into her own mouth before filling the container and handing it to a customer at the drive-thru. This behavior led to the charge of distributing food with a harmful substance.
The investigation gained momentum after a brief video of the act was posted to a private Snapchat story. While the video initially sparked national headlines, police used the drive-thru’s license plate records to identify the recipient of the fries. This tracking allowed investigators to establish a direct link between the employee and the customer, transforming a viral social media clip into a criminal case.
Targeted Contamination and Personal Conflict
The investigation revealed that the contamination was not a random act of employee misconduct but a targeted attack. Police reports state that Santos and the victim had dated for approximately two years before their relationship ended in late 2024. The victim told officers that Santos had been harassing her and her new partner prior to the incident.
The nature of the order on April 9 further underscores the targeted intent. The woman reported to police that she had only ordered sodas; however, she was handed a container of fries along with the drinks. The victim stated she only became aware of the contamination after she had already accepted and eaten the fries and subsequently saw the Snapchat video.
Managerial Failure and Operational Standards
From an operational standpoint, the incident represents a significant breach of food safety protocols, compounded by the seniority of the employee involved. Because Santos held a management position, police emphasized that her actions were a violation of the trust inherent in her role.
As a manager, Santos “was held to a higher standard as she was expected to lead the shift operations by ensuring high quality food, friendly service and overall cleanliness of not only of the restaurant but of the food being served as well,” Southbridge police wrote in the report. “In this case, Santos failed to adhere to the safe handling and cleanliness of the food provided to all customers including [the alleged victim]….
Southbridge Police Report
The breach of these standards suggests a breakdown in the internal controls designed to prevent food tampering. In the fast-food industry, managers are tasked with enforcing the very health and safety guidelines that Santos allegedly ignored. This creates a specific liability profile for the franchise, as the misconduct was committed by the person responsible for oversight during the night shift.
Implications for Franchise Risk Management
The case highlights the intersection of social media and corporate liability. The fact that the evidence was first disseminated via Snapchat demonstrates how private employee communications can quickly evolve into public relations crises and legal liabilities for a brand. For a global entity like McDonald’s, localized incidents of food contamination—especially those captured on video—can damage consumer confidence in food safety across the broader network.
The legal proceedings against Santos will likely focus on the intent and the potential health risks posed by the distribution of contaminated food. While it is not immediately clear if Santos has secured legal representation, the combination of surveillance footage and the victim’s testimony provides a concrete evidentiary trail for the prosecution.
The incident serves as a reminder of the vulnerability of drive-thru operations to internal bad actors. Unlike dining-room service, where multiple staff members may be visible, the drive-thru window often provides a more secluded environment for food preparation and hand-offs, increasing the risk of undetected tampering if managerial oversight is absent or, as in this case, the source of the problem.
