KIM LARSEN vs. UKIAH UNIFIED SCHOOL DISTRICT

The Workers' Compensation Appeals Board denied the defendant school district's petition for reconsideration of an award for acute myeloid leukemia. The Board found the applicant's exposure to diesel exhaust while employed by the school district was an injurious exposure contributing to the cancer. The Board ruled that the agreed medical evaluator's reports were admissible and constituted substantial medical evidence of the link between diesel exhaust and leukemia. Therefore, the school district was held liable as the last employer where the applicant was exposed to the hazard.

MARIA OCHOA vs. RANGERS DIE CASTING COMPANY, COMPWEST INSURANCE COMPANY

The Workers' Compensation Appeals Board (WCAB) granted reconsideration of a decision finding the applicant sustained injury to her respiratory system and psyche AOE/COE. The WCAB rescinded the decision and returned the case to the trial level, finding the medical opinions of Dr. Lipper and Dr. Curtis lacked substantiality. Specifically, the physicians failed to provide clear diagnoses, quantify exposures, or adequately explain causation. The Board noted contradictory testimony from the applicant's supervisor and insufficient evidence to support the initial findings.

JOSE CARRILLO (Deceased) ELVIRA CARRILLO (Widow) vs. ESTERLINE TECHNOLOGIES CORPORATION, ARCH INSURANCE, Administered by ESIS

The Workers' Compensation Appeals Board granted reconsideration of a taken nothing order concerning the death claim of Jose Carrillo, who died of renal cell carcinoma. The initial decision found the widow failed to prove her husband's cancer was industrially caused by toxic exposure during his employment. The Board found the Qualified Medical Evaluator's opinion equivocal and the record insufficient to determine the extent of the decedent's exposure to carcinogens. Therefore, the case was returned to the trial judge for further development of the record regarding chemical exposure and a new determination of industrial causation.

SHEILA CORREIA, KENNETH BURNETT (Deceased) vs. VERIZON COMMUNICATIONS, AMERICAN HOME ASSURANCE COMPANY, CHARTIS, SEDGWICK CLAIMS MANAGEMENT SERVICES

This case concerns a deceased worker, Kenneth Burnett, diagnosed with mesothelioma due to asbestos exposure. The sole issue was determining the date of last injurious exposure to establish liability. The Workers' Compensation Appeals Board denied reconsideration of the judge's decision. The judge found the applicant's medical expert's opinion on a five to ten-year latency period to be more persuasive than the defendant's expert's twenty-year period. This led to a finding that the decedent's last injurious asbestos exposure occurred between 1996 and 2001, during his employment with Verizon.

EDUBIJES TORREZ vs. RED HILLS COUNTRY CLUB, CHUBB SERVICES CORPORATION, STATE COMPENSATION INSURANCE FUND

The Workers' Compensation Appeals Board denied Chubb Insurance's petition for reconsideration, affirming the original finding that Edubijes Torrez sustained a cumulative trauma injury (leiomyosarcoma) due to chemical exposure as a groundskeeper. The Board found that despite the provision of protective gear in 1998, the applicant's exposure continued through his last year of employment, making Chubb, the insurer during that period, liable for the $100\%$ permanent disability award. Chubb's argument that exposure ceased in 1998 was rejected due to evidence of ineffective protective gear and continued exposure.

Joaquin Borges vs. COUNTY OF SANTA CRUZ

The Workers' Compensation Appeals Board granted reconsideration to reverse a finding that applicant Joaquin Borges sustained a cumulative trauma injury from asbestos exposure while employed by the County of Santa Cruz in 1989, resulting in colorectal cancer. The Board found insufficient substantial medical evidence to establish causation, noting Dr. Duncan's opinion relied on an inaccurate exposure history and lacked a clear dose-response analysis for non-asbestos worker exposure. The matter is returned to the trial level to determine if applicant is entitled to a presumption of injury under Labor Code section 3212.1.

SANDY BASTIAN vs. COUNTY OF VENTURA

This case involves a firefighter diagnosed with breast cancer who claimed industrial injury under California Labor Code section 3212.1. The defendant employer argued the statutory presumption of industrial causation was rebutted by an Agreed Medical Examiner's opinion stating the cancer was non-industrial, citing a lack of studies linking female firefighter exposures to breast cancer. The Appeals Board affirmed the WCJ's decision, finding the applicant sufficiently demonstrated exposure to carcinogens and the defendant failed to meet its burden to prove the exposure was "not reasonably linked" to the cancer. The court clarified that the mere absence of specific epidemiological studies does not rebut the presumption under section 3212.1.

JESSE CASTELLON vs. ORANGE COUNTY VECTOR CONTROL, ACCLAMATION INSURANCE MANAGEMENT SERVICES

The Workers' Compensation Appeals Board denied the defendant's petition for reconsideration of a finding that pesticide exposure contributed to the applicant's lymphoma, diabetes, and hypertension. The defendant argued the relied-upon medical expert erred by discussing Non-Hodgkin's Lymphoma instead of the applicant's diagnosed Hodgkin's Lymphoma. However, the Board found the expert's report sufficiently addressed Hodgkin's Lymphoma and its link to benzene exposure, incorporating the WCJ's reasoning. Therefore, the Board affirmed the original findings and denied the petition.

DANIEL JACOBS vs. WESTERN MUNICIPAL WATER DISTRICT, ACWA JOINT POWERS INSURANCE AUTHORITY

The Workers' Compensation Appeals Board denied the defendant's petition for reconsideration, affirming the finding that Daniel Jacobs sustained an industrial injury from Disseminated Coccidiomycosis. The Board found substantial evidence supported the original award, based on applicant's credible testimony regarding ongoing excavation and his extensive outdoor work at the 13-acre plant. The Board relied on the expert opinion of Dr. Sweeney, who stated with "very high medical probability" that the applicant's illness was work-related due to prolonged exposure to airborne fungus from disturbed soil. This employment exposed the applicant to a greater risk than the general public, thus meeting the legal standard for industrial causation.

STANLEY ANGEL (Deceased) WANDA ANGEL (Widow) vs. DOW CHEMICAL COMPANY, CRAWFORD & COMPANY, TRAVELERS

The Workers' Compensation Appeals Board reversed a prior finding that Stanley Angel's death from multiple myeloma was industrially caused by chemical exposure at Dow Chemical Company. The Board found insufficient evidence of sufficient exposure levels and duration to establish industrial causation. Medical opinions were split, but the Board found the applicant failed to meet the burden of proof for a causal connection. Consequently, the applicant received no further benefits.
