The biologic warfare program in Iraq began in the 1970s and was expanded in 1985. Two pathogenic bacteria were studied. For Bacillus anthracis, approximately 8000 L of solution with a spore and cell count of 109/mL were produced; 6000 L were used to fill weapons. The second pathogen was Clostridium perfringens; 340 L of solution were produced. Toxins were studied also. For aflatoxin (hepatotoxin, nephrotoxin, carcinogen), 2200 L were produced. For botulinum toxin, 20,000 L were produced, and 11,500 L were put in Scud missile warheads. Ricin is a potent toxin that has been used for assassination; 10 L of a concentrated solution were produced. Tricothecene mycotoxins were studied, and 20 mL were produced.
