at Texas Tech University raise questions
Since the mid-1990s, researchers at Texas Tech University (TTU) in Lubbock have conducted several projects to produce ricin, a toxin found in the seeds of the castor bean plant. Ricin is deadly in very small quantities and is subject to tight restrictions under both the Chemical and the Biological Weapons Conventions. At TTU, agriculture researchers bred castor to create high-ricin yielding plants specifically adapted for toxin production. TTU chemical engineers also built a machine to extract the highly potent toxin. The peaceful biomedical demand for ricin is extremely limited, and TTU’s efforts far outstrip it in many aspects. TTU's public explanation of all its ricin projects is required. The activities are of particular concern because of TTU's quiet but intense involvement in Pentagon biodefense programs.

Scale and Purpose: In many countries, castor is grown for its oil, which has many uses. In commercial castor production, ricin is a dangerous nuisance, and it is systematically eliminated from the oil and byproducts. TTU efforts work in the opposite direction - they relate to producing the toxin at a scale for which there is absolutely no legitimate use. A small plot of many existing types of castor will produce many times more toxin than is needed for legitimate biomedical purposes. With TTU's ricin extraction technology, even its small test plot is capable of producing enormous amounts of toxin. With normal harvests and farming practices, TTU's two acre (.81 hectare) plot, sown with an average ricin-level variety, can yield in excess of 150 kilograms of toxin if it is efficiently extracted. By way of comparison, the international terrorism scare prompted by last year's discovery of ricin in Europe was provoked by a few grams of the substance.

Conclusion: The effort at TTU to develop ways to produce and use ricin involved a coordinated effort across several academic departments and activities that, if conducted in many countries, the US would consider proof of a weapons program. While TTU is not the only university to experiment with transgenic ricin, the creation, much less release, of genetically-modified ricin-producing species is an extraordinarily bad idea. Either through accidents or abuse, such plants could result in widespread problems from ricin toxin. TTU's work to breed a ricin production variety of castor is completely unwarranted. Selection for ricin production characteristics should never have been performed, and the germplasm should not be released. TTU's construction of a ricin extraction unit in the absence of any legitimate demand for the weapons agent product was sheer folly.
