In two vague bills introduced both in the House and Senate of the US Congress, a vast reorganization of America's agriculture system aimed at tracking and regulating foods for public safety could endanger organic farms and gardens.  Provisions include mandatory registration and inspection for " any food establishment or foreign food establishment engaged in manufacturing, processing, packing, or holding food for consumption in the United States and sets standard practices such as minimums for fertilizer use.  Any food that the agency deems "unsafe, adulterated or misbranded" can be seized and the food establishment or farm fined.  HE LOOKS more like a genial uncle than a harbinger of doom, but the UK Soil Association's Patrick Holden visited Australia recently to deliver a sobering message.  Holden, the head of the Bristol-based charitable organisation that promotes organic farming, gave a series of public lectures in Sydney and met food industry figures at a private meal hosted by Kylie Kwong.  Sometimes referred to as the Al Gore of food security, Holden warned that if the west doesn't focus on shoring up food security it could leave itself open to a food crisis.
