OSHA Cites Wisconsin Food Manufacturer $364K After Two Kettle Failures Kill Three Workers in Janesville

Overview

OSHA cited IPMF LLC, operating as NaturPak, after two industrial-kettle incidents at its Janesville, Wisconsin plant released hot steam, liquid, and organic material — killing three workers and seriously injuring two. On February 12, 2026, a clogged vent line let pressure build until a kettle lid opened onto two employees; one suffered a concussion and one later died. On March 18, 2026, a second lid opened under pressure, burning three workers, two of them fatally. OSHA issued a serious citation for the kettle design and thermal-burn hazards, additional serious citations for exposing workers to thermal hazards without quick access to emergency water, an other-than-serious citation for failing to notify employees working adjacent to permit-required confined spaces, and repeat citations for fall hazards and for failing to develop, document, train on, and use lockout/tagout procedures. Penalties total $364,100 — $115,850 from the February 12 inspection and $248,250 from the March 18 inspection.

This enforcement action underscores the importance of proactive compliance and self-auditing. Below, we break down what was cited, why it matters, and what employers in similar industries should do now.

Compliance Timeline

Background and Context

The OSHA Regulatory Landscape

The Occupational Safety and Health Administration (OSHA) enforces workplace safety standards under the OSH Act of 1970, protecting approximately 130 million workers at 8 million worksites nationwide. OSHA sets and enforces standards, provides training and outreach, and conducts workplace inspections. For fiscal year 2025, OSHA's maximum penalties were adjusted to $16,550 per serious violation and $165,514 per willful or repeat violation — with annual inflation adjustments continuing to raise these ceilings.

OSHA enforcement priorities shift based on emerging hazards, workplace fatality trends, and National Emphasis Programs (NEPs). In recent years, the agency has intensified its focus on heat illness prevention, fall protection in construction, respirable crystalline silica, and workplace violence in healthcare. Employers in high-hazard industries should monitor NEP announcements closely, as these programs direct OSHA area offices to conduct targeted inspections in specific industries or for specific hazards even without a complaint or fatality trigger.

Why This Matters for Employers

Enforcement actions are one of the clearest signals of regulatory priorities. When OSHA or another agency cites specific violations, assesses penalties, and publicizes the case, it serves as both a deterrent and a roadmap. Employers in similar industries — particularly those with comparable operations, equipment, or processes — should treat this case as a direct prompt to audit their own programs.

The violations cited here point to specific standards that the agency considers high-priority for enforcement. Historically, citations in one region often precede increased inspection activity in the same industry nationwide as area offices share enforcement intelligence and target similar hazards.

Industry focus: This primarily affects employers in the Manufacturing sector. Organizations in this industry should evaluate their current compliance posture and determine if existing programs meet the updated requirements.

For employers reviewing their own practices, the key question is not whether a similar inspection will happen — it's whether your documentation and programs would withstand one. OSHA inspections can be triggered by employee complaints, referrals from other agencies, or programmed inspections under National Emphasis Programs.

Penalties and Enforcement Context

The proposed penalties in this case total $364,100. These amounts represent proposed penalties that may be adjusted through the informal conference process, formal contest before the Occupational Safety and Health Review Commission (OSHRC), or settlement. Penalties are typically calculated based on the gravity of the hazard, employer size, good faith, and violation history.
