Indoor production, strict protocols at Mt. Elliott farm aim to limit contamination
As state health officials reported nearly 1,300 cases of cyclosporiasis across the region, a Detroit-based vertical farm is highlighting practices it says keep produce protected from the parasite and other pathogens. Planted Detroit, located on Mt. Elliott Street, grows a range of leafy greens entirely indoors under a tightly controlled system designed to limit exposure to outside contaminants.
The facility’s chief operating officer, Darian Ahler, said the farm produces about 35 different varieties of greens, from romaine to arugula. The operation requires visitors and employees to don full personal protective equipment — described by Ahler as similar to protocols used in medical settings — before entering the nursery area.
"We do about 35 different varieties of greens," said Darian Ahler, chief operating officer of Planted Detroit.
Planted Detroit also conducts pre-plant testing of seeds for common foodborne bacteria, including E. coli, Listeria and Salmonella, and uses a filtered water supply for irrigation. Those measures are being emphasized as public-health investigators search for the source of the cyclosporiasis outbreak, which has raised concerns about contaminated food and water across the region.
What residents should know
- Planted Detroit’s indoor system aims to reduce contact with external contaminants such as soil, wildlife and surface water.
- Staff and visitors follow head-to-toe PPE protocols before entering the grow rooms.
- Seeds are tested for several bacteria before planting; water used on crops is filtered.
City residents who buy local produce may find reassurance in the additional testing and controlled-environment growing techniques used at indoor farms. At the same time, public-health officials continue to investigate broader sources of the outbreak; indoor farms represent one model of risk mitigation but do not on their own resolve community-wide exposure risks.

As investigators work to identify the source or sources of the parasite, Detroit growers and retailers may face questions from customers about sourcing and safety measures. Consumers seeking more immediate guidance should follow public-health advisories and check updates from state health officials as the investigation proceeds.
