Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, Scarlettah Schaefer

Journal of Food Law & Policy

Food and technology have had a long and tempestuous relationship. Current methods of food production and processing in the industrialized world depend heavily on technological developments. However, all technologies are not created equal. Some can produce food that is safer, more sustainable, more nutritious, or longer lasting. Some can have the opposite effect: increasing opportunities for adulteration, increasing the difficulty in detecting food fraud, and contributing to both foreseeable and unforeseeable health or ecological costs. Increasingly sophisticated technologies often become less apparent to the average consumer. For example, consider irradiated meat or genetically modified foods as opposed to freezer storage …

Acanthamoeba Spp. As Reservoirs For Transmission Of Norovirus, Tun-Yun Hsueh

Toward A Constructive Engagement: Agricultural Biotechnology As A Public Health Incentive In Less-Developed Countries, Chidi Oguamanam

Journal of Food Law & Policy

Discourses on global public health crises, especially as they impact the less-developed world, focus mostly on the issue of access to life-saving drugs for needy populations. Also, they implicate the misalignment of global pharmaceutical research and development (R&D) agenda with the health needs of the poor. Equally attracting significant attention is the role of intellectual property in driving up the cost of drugs and exacerbating the drug access freeze to needy populations. More often, the conceptual strings of these discussions are woven around a complex interaction of themes, including those of globalization, the development narrative, and strategic changes in international …

The History And Future Of Genetically Modified Crops: Frankenfoods, Superweeds, And The Developing World, Brooke Glass-O'Shea

Journal of Food Law & Policy

In a 1992 letter to the New York Times, a man named Paul Lewis referred to genetically modified (GM) crops as "Frankenfood," and wryly suggested it might be "time to gather the villagers, light some torches and head to the castle." Little did Lewis know that his neologism would become the rallying cry for activists around the world protesting the dangers of genetic engineering. The environmental activist group Greenpeace made great use of the "Frankenfood" epithet in their anti-GM campaigns of the 1990s, though they have since backed away from the word and the hardline stance it represents. But genetically …
