A longtime dairy plant is shutting down, and for anyone following food factory layoffs hitting familiar brands, this one has an especially painful local sting.
Guida-Seibert Dairy is permanently closing its New Britain, Connecticut facility this summer, a move expected to eliminate 205 jobs. The layoffs are scheduled to happen in phases, beginning around July 20 and wrapping up by August 31, according to a WARN notice filed with the Connecticut Department of Labor.
For Connecticut families, this is not just another corporate restructuring headline.

Guida’s name has been tied to milk, cream, ice cream, and local dairy history for generations. Seibert Dairy was founded at the current New Britain location in 1886. Alexander Guida Jr. started his own milk business in 1929, reportedly delivering 13 quarts of milk out of the back seat of his car. In 1947, the Guida brothers purchased Seibert Dairy and renamed the combined business Guida-Seibert Dairy Co., anchoring the New Britain plant in a long-running Connecticut dairy story.
That history makes the closure feel bigger than a factory shutdown.
Dairy plants are often invisible to shoppers until they disappear. People see the milk carton, the ice cream container, or the delivery truck, but not the workers, equipment, distribution routes, and local jobs behind them.
Now, more than 200 workers are facing job losses as the plant winds down.
The closure also lands at a difficult time for the broader food industry. Dairy companies have been dealing with changing consumer habits, higher operating costs, transportation challenges, private-label competition, and consolidation across the grocery supply chain.
Guida-Seibert’s parent company, Dairy Farmers of America, has owned the business since 2012. In April 2023, the company announced that Guida’s branded products would transition to its sister brand, Garelick Farms, also owned by DFA, with the messaging “same milk, new label.” The closure is another sign of how large food companies are reviewing older plants and deciding which facilities still fit their long-term plans.
For New Britain, the impact is local and immediate.
A plant that has been part of the region’s food economy for decades is going away. Workers will need to find new jobs. The city loses a familiar employer. And shoppers who grew up seeing the Guida name may wonder what happens next to a brand that felt close to home.
The dairy products may continue elsewhere under the Garelick Farms label. But the New Britain plant itself is reaching the end of the line.
After 140 years of dairy history tied to Connecticut, the closing marks the end of something that cannot be replaced by another carton on the shelf.
