Hawaii's Kauai Island moves to curb gene-altered crops, pesticide testing

Lihue, Hawaii (Reuters) - Lawmakers on the tropical island of Kauai, Hawaii, on Wednesday approved a hotly contested measure aimed at reining in widespread pesticide use by companies testing new genetically modified crops on the island.

The Kauai County Council passed the bill by a vote of six to one after months of protests by islanders and mainland U.S. groups who wanted to see a range of broad controls on the global agrichemical companies that have found the island's tropical climate ideal for year-round testing of new biotech crops.

The vote on Kauai came amid a global backlash against the spread of genetically-modified organisms in food and feed(GMO). Critics claim they contribute to greater pesticide use, environmental damage and health concerns for people and animals. But the industry says they are crucial for increasing global food production and improving environmental sustainability.

"This victory is an amazing credit to the people of Kauai who stood up to massive pressure from the GMO companies and won their right to know about pesticides and GMOs in their community," said Charles Margulis, a spokesman for the California-based Center for Environmental Health, which supported the bill.

Known as Hawaii's "Garden Isle," Kauai's landscape has become fertile ground for testing of new crops by DuPont Pioneer, Syngenta, BASF, and Dow AgroSciences, which together have staked out work on an estimated 15,000 acres on the isolated Hawaiian island.

DuPont, which fought to defeat the bill, was disappointed it passed, and may sue to block its implementation, said spokesman Josh St. Peters.

"We believe it to be bad policy - and the kind of regulation that should remain at the state and federal level, where policy makers and agencies are already empowered with oversight of our industry," he said. "We believe that the bill is not legally defensible and we continue to evaluate all of our business and legal options."

Kauai is the fourth largest of the main Hawaiian Islands and has a land area of 562.3 square miles and a population of about 67,000.

Many on the island have blamed health problems and pollution on what they say is excessive use of pesticides as the companies test a range of genetically altered crops. In early September, more than 3,000 islanders took to the streets of Lihue with signs and banners, and chanting "Pass the Bill."

More than 80 people lined up to offer testimony to the council meeting, which started on Tuesday morning but lasted until 3:30 a.m. local time on Wednesday. Only four people testified against the bill, the rest asked for its passage.

Early versions of the measure introduced in June prohibited open-air testing of experimental pesticides and genetically modified crops, established a permitting process for the industry and placed a temporary moratorium on the expansion of GMO crop test fields.

"The people in my community have asked for help," Kauai County Councilman Gary Hooser, who introduced the bill, said on Tuesday. "People are concerned."

In an attempt to forge compromise last month, Hawaii Gov. Neil Abercrombie proposed that pesticide and genetically engineered seed corporations be allowed to voluntarily disclose pesticide use.

The version of the bill that passed late Tuesday was stripped of some of its tougher conditions and now requires the agricultural companies to disclose the presence and use of genetically modified crops and pesticides; establishes buffer zones around schools, hospitals, homes and other areas, and requires the county to conduct a study on the health and environmental impacts of the industry.

Concerns about pesticide use on the island have been mounting in recent years and some allege health problems, including increased rates of cancer, are tied to the farm chemicals on the experimental crop fields.

But testifying at the hearing, BASF representative Kirby Kester said that passage of the bill was unwarranted because there is no evidence the companies are doing any harm.

And prior to the meeting, Mark Phillipson, spokesman for Syngenta Hawaii, said the industry was committed to a safe environment.

"We abide by high standards to create a safe environment for our workers, our neighbors and the community," Phillipson said.

A spokesman for Dow could not immediately be reached for comment.

New approaches for controlling pesticide exposure in children

Instead of relying too heavily on traditional pesticides, people should embrace “integrated pest management” measures, such as filling cracks in walls that let insects in and damp conditions that attract pests. Credit: Hemera/Thinkstock

New research on household pesticide contamination emphasizes the need for less reliance on pesticides and more emphasis on neatness, blocking cracks where insects can enter and other so-called "integrated pest management" (IPM) measures, scientists have concluded. Their study appears in the ACS' journal Environmental Science & Technology.

Chensheng Lu and colleagues cite previous studies showing that urban, low-income, multifamily, public housing dwellings are prone to severe pest infestation problems. Families in Boston public housing developments, for instance, rank pest infestation, pesticide use and pest allergies second only to crime as matters of concern. In an effort to encourage use of IPM, which reduces reliance on traditional pesticides, Lu's team studied exposure to 19 pesticides among children in 20 families in Boston's public housing.

They found pesticides in all of the homes, along with indications—such as sighting of live pests or pest debris—that traditional pesticides were not effective. "The results from the current study, as well as other recent studies, conducted in low-income public housing, child care centers and randomly selected homes in the U.S. should accentuate the need for alternative pest management programs," the report states. IPM focuses on eliminating the cause of pest infestations by minimizing access to food, water, hiding places, and sealing cracks and other openings in walls to prevent entry of pests.

Abstract
We designed this community-based participatory research (CBPR) project aiming to generate evidence-based research results to encourage residents living in urban low-income public housing dwellings engaging in a community-wide integrated pest management (IPM) program with the intention to improve their health and quality of life, as well as household conditions. We enrolled 20 families and their children in this study in which we utilized environmental exposure assessment (surface wipe and indoor air) tools to quantitatively assessing residential pesticide exposure in young children before the implementation of an IPM program. We analyzed those samples for 19 organophosphate (OP) and pyrethroid pesticides.
The most commonly detected pesticides were pyrethroids, particularly permethrin and cypermethrin with average concentrations of 2.47 and 3.87 µg/m2, respectively. In many dwellings, we detected OPs, which are no longer available on the market; however, their levels are significantly lower than those of pyrethroids. None of the 20 families was free from pesticide contamination in their households, and pesticides were commonly detected in living room and children's bedroom.
The correlation among household hygienic conditions, the sighting of live pests/pest debris, and the degree of indoor pesticide contamination highlights the failure of conventional chemical-based applications for pest controls. The results from the current study, as well as other recent studies, conducted in low-income public housing, child care centers, and randomly selected homes in the U.S. should accentuate the need for alternative pest management programs that incorporate safer and more sustainable protocols for pest controls.
