Free-living Cucurbita pepo in the United States
Viral Resistance, Gene Flow, and Risk Assessment
Epilogue
....We are living in a time when the public trust in science and scientists is at its lowest (4).  A major reason for this regrettable turn of events is the commercialization of science (4).  We do nothing to better this situation by allowing prestige and money to drive decisions rather than true insight and a striving toward a better future for this planet and the myriads of diverse creatures living on it, including our own kind"

This page is under constant, albeit sporadic, construction.  It will carry information that I have been able to glean regarding new developments on the ZW-20 (now evidently trademarked as 'Freedom II') release and related matters.

This release was a minor regulatory difficulty for the biotech industry. Federal approval of the ZW-20 petition set a precedent that has allowed rapid review/approval of subsequent petitions for commercial release of transgenic lines. This, in turn, has forced a more focused examination of biological impacts of 'escaped' transgenes. Developments in this area, especially information available via the internet, will be recorded here. Information for posting on this page can be sent to Hugh Wilson.

This issue provides a direct interface with a fundamental problem - those agencies of the U.S. government responsible for regulating commercial activities are usually involved with the promotion of those activities.  This promotional function, and concordant close association with the industry, is clearly expressed by the USDA-APHIS-BSS website and the simple fact that this unit has rarely - if ever - declined a permit request from the biotech industry.  The classic 'revolving door' signal of governmental corruption is also present (see 'un-safe science' for more detail).

My contact person at USDA-APHIS for this report was Dr.Val Giddings.  According to Corporate Watch (see Government Workers Go Biotech):
 

"Also putting on the industry hat this month was L. Val Giddings. Less than two weeks ago, Giddings' went from being a biotechnology regulator at the United States Department of Agriculture (USDA/APHIS) to being the vice president for food and agriculture at the Biotechnology Industry Organization (BIO).  Giddings, who had been a member of the U.S.  delegation at the first meeting of the Open Ended Ad Hoc Working Group on a Biosafety Protocol, attended last week's second meeting on the protocol as the representative of BIO."
This oversight process included rigorous review and preparation of site-specific environmental assessments for each field test...(Dr. Giddings on the job)

The Asgrow Seed Company, producing of the ZW-20 squash and a subsidary of the Upjohn Company when this report was produced, was evidently sold in 1995, to Empressas La Moderna (ELM), an affiliate of the Pulsar Internacional group of companies based in Monterrey, Mexico.  The Monsanto Company, winner of a recent greenwash award, purchased Asgrow Agronomics from Mexico's Empresas La Moderna (ELM) in 1996 for $240 million.  However, this report suggests that the topic of the report presented here - Asgrow's ZW-20 squash (known as 'Freedom II') - is no longer on the market and this product is no longer a part of Asgrow's history.
