Based on my review of the evidence as well as my consideration of the relevant provisions of the Missouri Workers' Compensation Law, I am convinced the decision of the administrative law judge awarding benefits to employee was in error, and should be reversed.
Employee alleges she was exposed to pulmonary disease while power washing animal stalls, pens, and pits in employer's hog farm. On April 30, 2002, employee was admitted to the Wayne County Hospital with complaints of worsened respiratory functioning. A chest xray revealed substantial pneumonia in both lungs. Owing to the seriousness of employee's condition, treating doctors sent her via helicopter to Mercy Hospital in Des Moines, Iowa, where employee was placed on a ventilator and given a breathing tube. Treating doctors diagnosed Legionnaires' disease. Employee contends that she contracted Legionnaires' disease while performing her power washing duties for employer.
Employer presented testimony from its director of environmental health and safety, Brian Paulsen. Mr. Paulsen explained that the water source utilized for power washing goes through three separate disinfection safeguards. First, the water is chlorinated using an automatic hypochlorination process that kills bacteria present in the water. Then, the water is filtered to remove any residual contaminants. Finally, the water is heated to a temperature sufficient to effectively kill any bacteria still remaining. Mr. Paulsen identified the results of water sample testing performed subsequent to employee's getting sick in April 2002. Those test results demonstrate that no Legionella bacteria were present in the water source used for power washing.
Employer presented the expert medical testimony of Dr. David McKinsey, an infectious disease specialist. Dr. McKinsey opined that no causal link can be drawn between employee's work for employer and her development of Legionnaires' disease. Dr. McKinsey explained that if Legionella pneumophila, the causative agent of the disease, were present in the workplace, it would be expected to cause multiple individuals to develop an infection. (As confirmed by Mr. Paulsen, no other employees had contracted Legionnaires' disease from 2001 to the present.) Dr. McKinsey found it notable that the samples of water taken from the workplace were negative for Legionella. Dr. McKinsey explained that even if there had been a negligible potential risk of occupational exposure to Legionella from using high pressure hoses, the risk was mitigated by the process of heating the purified water to a temperature greater than 160 degrees Fahrenheit.
Employer also presented testimony from Dr. Barkman, a pulmonary specialist, who explained that there were multiple factors unrelated to employee's work that put her at risk for suffering pulmonary injury in the form of pneumonia, namely her history of smoking and alcohol abuse. (Employee smoked two packs of cigarettes per day for about 20 years, and at the time of the alleged work injury, she was drinking between 6 and 10 beers daily.) Dr. Barkman opined that employee suffered a community-acquired pneumonia in April 2002, and that her work was not a substantial factor in causing it. Dr. Barkman explained that employee's primary problem is her preexisting chronic obstructive pulmonary disease, and that the pneumonia resolved and had little effect on her underlying chronic condition.
I find the testimony and opinions from Dr. McKinsey and Dr. Barkman in this matter to be credible and more persuasive than those provided by employee's expert, Dr. Beller. Unlike Dr. McKinsey, Dr. Beller (who is not an infectious disease specialist) did not review any information relating to methods by which employer disinfects the water used for power washing. Dr. Beller also relied on incorrect facts contained in correspondence from employee's counsel, including the assertion (disproven by the testimony from Mr. Paulsen) that many employees got sick while working for employer, as well as a completely false account of the process in which water arrived at the hoses employee used for power washing. Specifically, employee's counsel told Dr. Beller that the water came from a holding tank supplied by a pond which consisted of "ground water percolating through or over fields fertilized by manure lagoon sludge." See Transcript, pages 414-15, 469. As demonstrated by the testimony from Mr. Paulsen, none of this is true. Because Dr. Beller relied on false information supplied by employee's counsel, his testimony cannot support an award in favor of the employee.
The versions of $\S \S 287.067 .2$ and 287.020.2 RSMo applicable to this claim require an employee claiming injury by occupational disease to prove that work was a substantial factor in causing the injury. Given my findings regarding the expert medical testimony, I conclude employee failed to meet her burden of proof. I conclude that employee's work for employer was not a substantial factor in causing employee to suffer pneumonia or Legionnaires' disease. Because I am convinced employee failed to prove that she suffered injury by occupational disease, I would deny employee's claim against both the employer and the Second Injury Fund.
Because the majority has determined otherwise, I respectfully dissent.
