The outbreak has been linked to the chain’s two restaurants in Arapahoe County and El Paso County, both of which opened last month.
Another 25 employees are potentially infected, but they have not been tested, according to the agency’s weekly report.
The employees who have tested positive along with the employees who had close contact with them "have been excluded from the workplace," In-N-Out’s Vice President of Operations Denny Warnick said in a statement.
"Nothing is more important to us than the health and safety of our Customers and Associates. We are committed to doing our part in preventing the transmission of the COVID-19 virus," Warnick said. "Our thoughts and prayers are with our Associates and we are hopeful for quick recoveries for each of those affected."
In-N-Out Burger is reportedly working with public health agencies and has "confirmed the appropriate steps" to take in response to the current pandemic.
This includes limiting staff capacity in restaurants, minimizing contact with customers, reserving dining room access for takeout orders, ensuring social distancing and providing hand sanitizer at every location.
Additionally, self-service drink stations are temporarily closed while contactless payment options are available.
Employees are required to wash their hands and disinfect restaurant surfaces regularly. Health screenings and temperature checks are administered before shifts, however, employees who feel sick are advised to stay home per In-N-Out’s COVID-19 policy.
