HASTINGS, Mich. — Officials confirmed that testing has detected ricin at Tyden Lofts after 145 residents were evacuated from the apartment complex following a possible exposure tied to a tenant who sought care at a local hospital, the Barry-Eaton District Health Department said.
Immediate response and investigation
The department said the incident began when an individual arrived at Corewell Health Pennock Hospital reporting a potentially hazardous substance that had been produced in their unit. That person was isolated, and authorities notified the Barry-Eaton District Health Department (BEDHD) and federal agents. By Friday, local public-health officials and the FBI were working together to investigate what was initially believed to be a ricin exposure.
On Saturday, BEDHD announced that confirmatory testing had established the presence of ricin at the Tyden Lofts site. Response teams moved from initial containment into an environmental sampling phase aimed at determining the presence and extent of contamination and whether additional remediation is required.
"I think something else that's really concerning is how a very small amount of it can be extremely toxic," Emily Smale, communications specialist for the BEDHD, said.
Health officials urged that residents remain away from the building until authorities declare it safe. "This is an important next step toward allowing residents to safely return to their homes," the department said, and added that it understands the difficulty faced by residents and their families during the uncertainty.
Health risks, testing and those affected
Ricin is a natural toxin derived from castor beans or castor oil and can be harmful if swallowed, inhaled or injected. The BEDHD noted people could also be exposed by touching contaminated clothing or by inhaling ricin in a powdered form.
Authorities offered testing to tenants and employees of Tyden Lofts as well as to first responders who had potential exposure concerns. The department also indicated that response teams would determine whether additional cleanup or other actions are necessary based on environmental sampling results.
- Evacuated: 145 tenants from 61 units
- Initial isolation: the person who arrived at the hospital
- Agencies involved: Barry-Eaton District Health Department and the FBI
- Next step: environmental sampling and possible decontamination
Practical implications and precautions
Officials stressed that the incident appears isolated but noted the high toxicity of small amounts of ricin. They cautioned that until sampling and any required cleanup are complete, residents should not return to their units. Fire departments and public-health teams often follow a sequence of containment, sampling and remediation to ensure safety; that process could prolong displacement for affected tenants depending on sampling findings.

The BEDHD said it is coordinating with federal and local partners to complete sampling and to communicate results and next steps to residents and the public. Authorities have not released additional details about the individual who initially sought care, nor have they provided a timeline for when residents might be allowed to return.
As sampling proceeds, health officials emphasized caution and testing for anyone who believes they may have been exposed. The department also noted that pets were part of responders' considerations, and firefighters had been involved in initial actions at the scene.
Investigations into incidents involving ricin typically include law enforcement forensic analysis in addition to public-health testing, and federal participation reflects the potentially criminal nature of such exposures. Authorities continue to gather data to determine contamination extent and to make decisions about cleanup and resettlement of residents.
Officials said they are working to move "as quickly as possible to move as safely as we can through this process" while ensuring public safety and transparency for residents affected by the evacuation.
