An experienced Iowa mesothelioma attorney should review your case immediately — not next month, not after the holidays.

You May Have Legal Rights Worth Pursuing

If you worked at the Oscar Mayer Foods processing facility in Perry, Iowa — or if a family member did — and you have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, your legal rights may be substantial. For decades, workers at this facility may have been exposed to asbestos-containing materials that manufacturers including Johns-Manville, Owens-Illinois, Combustion Engineering, Armstrong World Industries, and W.R. Grace are alleged to have known posed serious health risks — and continued selling without adequate warnings anyway.

This page explains what likely happened at the Perry plant, which workers were most at risk, what diseases result from that exposure, and what legal options remain available to you today.

The Oscar Mayer Foods Facility in Perry, Iowa

A Major Industrial Employer in Central Iowa

The Oscar Mayer Foods processing facility in Perry, Iowa was one of the meatpacking and food processing operations that defined central Iowa’s industrial economy for much of the twentieth century. Perry, a small city in Dallas County approximately 40 miles northwest of Des Moines, built substantial portions of its local economy around this large-scale food processing operation. The plant employed hundreds of workers over multiple decades — pipefitters, boilermakers, electricians, mechanics, and production staff who spent careers inside its walls.

Why Food Processing Facilities Like Perry Used Asbestos-Containing Materials

Large-scale industrial food processing facilities built and expanded in the United States from the early twentieth century through the 1980s depended on industrial systems that the construction trades routinely insulated and serviced with asbestos-containing materials. At the Perry Oscar Mayer plant, those systems allegedly included:

High-pressure steam boiler systems for cooking, sterilization, and facility heating
Extensive pipe networks carrying steam, hot water, condensate, and process fluids throughout the plant
Industrial smokehouses and cooking ovens requiring sustained high-temperature operation
Refrigeration compressor systems and associated pipe insulation for cold storage
Turbines and pumps with heat-generating mechanical components
Electrical switchgear and panel systems requiring fire-resistant insulation

From the 1920s through the late 1970s, asbestos-containing materials were the universal industrial solution for all of these applications. Manufacturers including Johns-Manville Corporation, Owens-Illinois, Combustion Engineering, Pittsburgh Corning, Armstrong World Industries, Georgia-Pacific, and Celotex aggressively marketed asbestos-containing products to industrial customers like Oscar Mayer. Internal corporate documents produced in asbestos litigation have established that these manufacturers knew for decades that their asbestos-containing products posed serious health risks to workers — and continued marketing them without adequate warnings regardless.

Who Worked at the Perry Plant and May Have Been Exposed?

Occupational medicine research consistently shows that skilled tradespeople who worked daily alongside asbestos-containing materials in industrial settings carry the heaviest cumulative asbestos exposure burdens. The following trades represent the populations most likely affected at the Perry facility.

Insulators (Heat and Frost Insulators)

No trade carries a heavier asbestos exposure burden than insulators — a finding recognized consistently across decades of occupational health research. At a facility like the Perry plant, insulators allegedly worked routinely with asbestos-containing pipe covering products such as Kaylo and Thermobestos, boiler block insulation, and equipment insulation. Cutting, fitting, and applying these materials generates extremely high airborne fiber concentrations. Insulators represented by Heat and Frost Insulators Local 1 (St. Louis) and Local 27 (Kansas City) who worked at this facility may have been exposed to asbestos-containing materials throughout their careers.

Pipefitters and Steamfitters

The Perry facility’s steam and process piping systems required constant maintenance and repair. Pipefitters and steamfitters represented by Plumbers and Pipefitters UA Local 562 (St. Louis) and Local 268 (Kansas City) allegedly encountered asbestos-containing pipe insulation covering extensive pipe runs throughout the plant. Flange work, valve replacements, and pipe repairs routinely required cutting away or disturbing surrounding insulation — releasing asbestos fibers into the worker’s breathing zone. Pipefitters at facilities of this era also regularly handled asbestos-containing gasket and packing materials, including products allegedly manufactured by Garlock Sealing Technologies, used to seal flanges and valves under high-pressure steam conditions.

Boilermakers

The facility’s boiler systems — essential for generating the steam used in cooking, sterilization, and plant heating — were allegedly insulated with asbestos-containing boiler block and sectional insulation. Boilermakers who inspected, repaired, retubed, or rebuilt boilers at this facility may have encountered asbestos-containing materials in concentrated quantities. Boiler interiors were commonly lined with asbestos-containing refractory and insulating cements. This work frequently occurs in confined spaces where disturbed asbestos fibers have nowhere to go.

Electricians

Electricians in industrial facilities of this era may have been exposed to asbestos-containing materials through multiple pathways. Electrical wiring and components manufactured during this period often incorporated asbestos-based insulation on wires, in panelboards, and in switchgear. Electricians also routinely worked alongside insulators and pipefitters — placing them squarely within the “bystander exposure” category that occupational medicine has long recognized as generating disease-causing fiber burdens. Electricians at the Perry facility who worked near ongoing insulation or maintenance work may have been exposed to products including Monokote and Aircell fireproofing materials.

Maintenance Mechanics and Millwrights

General maintenance workers and millwrights at the Perry facility may have encountered asbestos-containing materials throughout the plant in the course of routine work orders. Replacing gaskets, repairing pipe systems, working in boiler rooms, and performing general upkeep all brought these workers into contact with asbestos-containing materials allegedly manufactured by Johns-Manville, Owens-Corning, and Garlock Sealing Technologies — often without any warning of the hazard involved.

Refrigeration Mechanics

Meatpacking facilities depend entirely on refrigeration. The Perry plant’s refrigeration systems — including compressors, condensers, evaporators, and associated pipe networks — required insulation and ongoing mechanical maintenance. Refrigeration mechanics at this facility may have been exposed to asbestos-containing pipe insulation on cold lines, as well as gasket and packing materials used in refrigeration compressors and associated equipment allegedly manufactured by Crane Co. and other industrial suppliers.

Production Workers and Maintenance Support Staff

While the highest exposures are typically documented among skilled tradespeople, production workers who spent time in areas where asbestos-containing materials had deteriorated — or where nearby maintenance work was underway — were also at risk. Asbestos fibers released during maintenance activity do not respect departmental boundaries. Production workers who regularly passed through or worked near boiler rooms, pipe chases, or mechanical spaces may have been exposed without ever picking up a tool.

Construction and Renovation Contractors

Over a facility’s decades-long operational life, contractors performing construction, renovation, and expansion work entered the plant repeatedly. These workers may have disturbed existing asbestos-containing materials — including products such as Unibestos, Cranite, and Gold Bond insulation — or introduced new asbestos-containing products to the site. They may not appear in Oscar Mayer’s own employment records, but they remain a fully recognized potentially exposed population in asbestos litigation.

When Workers at Oscar Mayer Perry May Have Been Exposed

The Primary Exposure Window: Approximately 1940–1980

Based on what is known about comparable food processing and meatpacking facilities of the same era and region, asbestos-containing materials at the Perry Oscar Mayer plant were allegedly used most heavily during the period spanning roughly the 1940s through the late 1970s.

Pre-1970s Installation and Construction

When the facility’s major systems were built or expanded, asbestos-containing pipe insulation, boiler block insulation, and related materials were the standard industrial specification nationwide. Contractors building and commissioning these systems routinely worked with products allegedly manufactured by Johns-Manville, Owens-Illinois, and Armstrong World Industries. Workers involved in that construction and initial commissioning may have been exposed during those periods.

The Post-OSHA Transition Period: 1972–1985

OSHA’s initial asbestos standards, promulgated in the early 1970s, began curtailing new asbestos-containing material installations. But existing materials already in place at facilities like Perry remained where they were, often for years or decades afterward. Workers during this transitional period may have been exposed to deteriorating asbestos-containing materials even as new installations declined — sometimes with no greater warning or protection than workers had received a generation earlier.

Repair, Renovation, and Routine Maintenance

A substantial portion of industrial asbestos exposure occurs not during original installation but during subsequent repair, renovation, and maintenance of systems already in place. Workers who cut, sawed, sanded, or otherwise disturbed previously installed asbestos-containing pipe insulation, boiler block, floor tiles, ceiling tiles, or gasket materials — allegedly manufactured by Johns-Manville, Garlock Sealing Technologies, and others — may have been exposed to fibers that had been in place for decades. This category of exposure continued in many facilities well into the 1980s and beyond.

Asbestos Abatement Activities

Facilities of this type typically underwent asbestos surveys and abatement beginning in the 1980s and 1990s as EPA NESHAP regulations governing asbestos removal took effect. Abatement records, where they exist, can serve as documentary evidence in litigation — establishing what asbestos-containing materials were present, in what quantities, and where they were located throughout the facility.

What Asbestos-Containing Materials May Have Been Present?

The presence of any specific product at this facility must be established through litigation discovery — facility records, product identification testimony from former workers, and manufacturer distribution records. Based on what is documented about comparable industrial food processing facilities of the same era and region, workers at the Perry Oscar Mayer plant may have been exposed to asbestos-containing materials in the following product categories:

Pipe and Block Insulation

Asbestos-containing pipe covering products including Kaylo and Thermobestos, allegedly manufactured by Johns-Manville and other suppliers
Magnesia block insulation on high-temperature pipe segments
