By 1933, distribution of Boar's Head products had grown, and Brunckhorst and his partners, Bruno Bischoff and Theodore Weiler,[3] decided to open a manufacturing plant.

[4] During the 1990s, the expanding company added processing plants in Virginia, Arkansas, and Michigan,[5] and it began to shift its strategy toward its current business model that stresses exclusive relationships with supermarket chains.

[12] With an initial reported case of illness on May 29, 2024, the U.S. Centers for Disease Control and Prevention (CDC) determined a listeriosis outbreak traced to Boar's Heads products, linked to 10 deaths and 59 hospitalizations as of September 25, 2024.

[17] Ongoing monthly inspections from August 2023 through July 2024 at the Jarratt plant reported black mold, surfaces contaminated with "meat over-spray", and an unknown substance dripping from the ceiling.

[18][19] Multiple lawsuits were filed against Boar's Head following the listeria outbreak alleging a wide range of complaints from false advertising to wrongful death.
