Corning Incorporated

The Hot Zone

Corning Incorporated enters the narrative through a network of animal-research businesses, most consequentially the company’s Hazleton division and its Reston Primate Quarantine Unit. The unit’s work importing and holding laboratory monkeys placed a commercial animal facility at the center of the 1989 Reston outbreak and the response that followed.

Corporate Structure

Hazleton Research Products was a division of Corning Incorporated involved in importing and selling laboratory animals. Corning also owned Hazleton Washington, a separate company whose headquarters stood on Leesburg Pike. The account distinguishes the two businesses while locating both within Corning’s corporate orbit: Hazleton Research Products operated the monkey facility, while Dan Dalgard was a principal scientist at Hazleton Washington.

Animal Importation and Quarantine

The Reston Primate Quarantine Unit occupied a one-story building in an office park in Reston, Virginia. Each year, about 16,000 wild monkeys were imported into the United States, and imported animals had to be kept in quarantine for a month before shipment onward. The requirement was intended to prevent infectious disease from spreading to other primates, including humans.

On October 4, 1989, Hazleton Research Products accepted a shipment of 100 wild monkeys from the Philippines. They had come from coastal forests on Mindanao, passed through Ferlite Farms, and traveled by air to New York before being trucked to Reston. The monkeys were Crab-eating macaques, commonly used as laboratory animals because they were readily available and inexpensive. Their route from capture and holding facility to quarantine station made the Reston unit one link in a wider animal-supply chain.

Staff and the Reston Facility

Dan Dalgard served as the Reston unit’s consulting veterinarian, on call when monkeys became sick or needed medical care. His principal-scientist position was at Hazleton Washington, whose nearby headquarters made it practical for him to drive to the monkey house when needed. The distinction between his two roles connects Corning’s separate operations through the work of a single veterinarian without making the companies or facilities interchangeable.

When illness among the monkeys raised concern about the facility, the monkey house became the focus of reconnaissance and containment planning. Army personnel assessed its rooms and routes of entry, while the risks at the site also extended to laboratory workers handling monkey tissues and blood at Hazleton Washington’s offices. These events show how the company’s animal-import business brought together a quarantine building, veterinary care, and human contact with animal specimens.

Outbreak Response and Aftermath

The response at the monkey house was carried out by government and military teams, not described as a Corning operation. After the animals and facility became the subject of the emergency response, a decontamination team scrubbed the building with bleach, sealed its exterior openings, and used formaldehyde gas. The treatment lasted three days and was followed by testing with harmless bacterial spores; the samples were killed, and the account describes the unit as sterilized. Corning’s significance here is therefore structural rather than operational: its subsidiary’s quarantine facility was where an imported-primate outbreak became a major containment problem.
