The judicial decision reached on Tuesday afternoon in Trikala has sent shockwaves through the Greek business community, as Konstantinos Tziortziotis, the man behind the "Violanta" biscuit empire, was remanded in custody. The decision followed an exhaustive four-hour and 45-minute testimony, during which the entrepreneur was called to account for the tragedy on January 26, 2026. A massive explosion at the company’s factory claimed the lives of five female employees.

The chronicle of the case, as documented through harrowing employee testimonies, expert findings, and revelations of substandard maintenance, paints a picture of a "chronicle of a death foretold."
The explosion that leveled the "B" Wing of the Violanta factory was not a bolt from the blue. According to case file evidence, the propane leak that caused the disaster had been noticed by staff at least two months before that fateful dawn.
Employees testifying before investigative authorities described a nightmare daily routine. Since early December 2025, a strong smell of gas had been lingering in the production areas, centered around the restrooms and the washing area. "The smell was so intense that our eyes would sting," testified a worker who had been with the company for 24 years. Despite constant complaints to supervisors and management, the response was always the same: "It’s from the cesspools; we’ll put some medicine in to make it pass."
Management’s insistence on attributing the propane smell to the sewage system proved fatal. As it turned out, it was not the stench of waste, but a buildup of flammable gas in the subsoil, seeking an outlet through the building's plumbing.
"Amateur" Installations and Illegal Practices
One of the most shocking aspects of the case is the revelation that the critical gas infrastructure was maintained and installed by individuals lacking the necessary expertise.
In his testimony, the man performing the duties of a plumber at Violanta admitted that he held no certification or license as a propane gas installer. Nevertheless, he claimed that eight years ago, Konstantinos Tziortziotis himself tasked him with setting up the new gas line for the cereal production unit, fully aware of his lack of qualifications.
The "amateur" technician testified that he had noticed the smell and reported it to the owner. He described a state of total indifference: "The production manager told me to say the smell was coming from the cesspools until we figured out what was happening." Furthermore, he revealed that for the last month and a half, there was a visible loss of gas pressure in the ovens—a clear sign of a leak that was blatantly ignored.
The mechanical engineer who conducted the forensic audit of the destroyed facilities was damning. Using specialized detection equipment, he found that the underground steel pipe transporting propane from the tanks to the ovens had suffered severe damage.
Because propane is heavier than air, it did not dissipate into the atmosphere but "soaked" the ground and accumulated in the basement of Wing B. The measurements showed shock values: 2,500 ppm in the soil and 6,000 ppm inside the basement. At these levels, the basement had turned into a giant bomb waiting for a spark. That spark reportedly came from an electric motor during the night shift, triggering the explosion that leveled the building and killed the five workers.
During his testimony, the owner of Violanta was confronted with hard questions and audiovisual material from the moment of the catastrophe. According to reports, he declared himself "devastated" and claimed he was unaware of the danger's magnitude. "My children used to play in that area," he reportedly said, attempting to convince authorities that he would never have endangered his family had he known the truth.
However, his claims of ignorance collapsed in the face of testimonies placing him as informed about the odor. Tziortziotis reportedly shifted blame onto his associates, pointing to individuals who signed off on safety and claiming that reports regarding the problem's severity reached his ears "far too late."
Beyond the leak, the investigation brought to light a generalized culture of negligence. Employees testified that:
-
No emergency training or evacuation drills had ever taken place.
-
Electric shocks occurred frequently due to cables on the floor, but management dismissed them as "routine minor accidents."
-
Official inspections (such as EFET) were usually limited to Wing A—the factory’s "showroom"—while Wing B, where heavy production occurred, remained in the dark.
The remand of Konstantinos Tziortziotis is a resounding response from the justice system, but for the families of the five women, the road is still long. The Violanta case is not merely an industrial accident; it is a reminder of what happens when profitability is placed above safety and the "smell of gas" is rebranded as "sewage odor" to keep the machines running.
The owner is expected to be transported to Trikala Prison, while the investigation continues to assign responsibility to other company executives involved in concealing the deadly risk.
