The site in the Springdale Technology Park means the microbiology lab has more than doubled.
The company employs 19 people having added six positions within the last two years.
Whitbeck Laboratories offers a laboratory for the food and poultry industries as well as diagnostic services for local veterinarians.
The company works with food industry research and development companies, providing facilities and testing.
Gordon Whitbeck, company president, said food safety is of the utmost concern for anyone in the business.
“With the dramatic increase in food safety regulations and policies by federal regulators and food producers, we have seen a significant increase in the demand for the services our lab offers.”
Whitbeck Laboratories holds National Poultry Improvement Plan (NPIP) certification and will host training seminars required by the NPIP program.
In 2012, Whitbeck Labs acquired The Poultry Federation laboratory in Fayetteville to add serology assays and it bought A&A Laboratories in 1989 to add chemistry testing.
