Project Summary Chemistry – Animal Food The production of safe, high quality commercial feeds and grain is critical for maintaining Iowa’s livestock inventory, including Iowa’s first in the nation ranking in hogs and egg-laying chickens, third in milk goats, and forth in cattle and calves feed. According to the Institute for Feed Education and Research (IFEEDER), a non-profit founded by the American Feed Industry Associates, Iowa leads the nation with over 21 million tons of total animal food consumed (IFEEDER, 2017). On any given day, there are over 100 million livestock animals consuming feed on Iowa farms (USDA, 2019). The meat, milk and eggs produced from Iowa livestock are consumed across the nation and around the world, which makes the quality of Iowa animal feeds vital to human food safety, as well, For example, in 2018 Iowa exported pork products to 33 countries according to Iowa Economic Development Authority (IEDA, 2019). Chemical and Biological contaminants in feed may accumulate in the tissue and fat of meat-producing animals. As the contaminants move up the food chain, the hazard from the contaminant can be magnified. Animal feed safety also includes food for a special subset of animals—pets. Pet illnesses caused by contaminated food tend to generate a high number of consumer complaints and attract a significant amount of media coverage. Iowa has 20 pet food facilities processing over 490,000 tons of ingredients into pet food every year (IFEEDER, 2020). A panel of mycotoxins chosen for testing under this cooperative agreement are three of greatest concern in Iowa feed: aflatoxins, fumonisins, and zearalenone. Two hundred animal feed samples and 100 pet food samples will be tested for mycotoxins. Another threat to animal feed is contamination with toxic elements. Metals can be toxic at very low doses. Toxic metals enter the animal food supply from the environment (through plants and water), but can also be leached from containers or utensils in direct contact with the food. They are non- biodegradable and difficult to excrete, leading to accumulation in tissues and toxicity. Metal accumulation increases for animals higher in the food chain. Two hundred mineral samples will be tested for heavy metals. These data will be shared with FDA and the results will mold the future years of this project.

项目概要化学-动物食品 生产安全、高质量的商业饲料和谷物对维持爱荷华州的 牲畜库存，包括爱荷华州在全国排名第一的猪和蛋鸡， 奶山羊，并在牛和小牛饲料。根据饲料教育研究所和 研究（IFEEDER），一个由美国饲料工业协会成立的非营利组织，爱荷华州领导了 中国的动物性食品消费总量超过2100万吨（IFEEDER，2017）。在任何一天， 超过1亿头牲畜在爱荷华州农场食用饲料（USDA，2019）。肉，牛奶， 产自爱荷华州牲畜的鸡蛋在全国和世界各地都有消费，这使得 爱荷华州动物饲料的质量对人类食品安全至关重要，例如，2018年爱荷华州出口 根据爱荷华州经济发展局（IEDA，2019）的数据，猪肉产品出口到33个国家。 饲料中的化学和生物污染物可能会在产肉动物的组织和脂肪中积累， 动物随着污染物沿着食物链向上移动，污染物的危害可能是 放大了动物饲料安全还包括一种特殊动物--宠物的食品。宠物疾病 由受污染食物引起的食物中毒，往往会引起大量的消费者投诉， 大量媒体报道。爱荷华州有20个宠物食品加工设施， 每年都会将成分添加到宠物食品中（IFEEDER，2020）。选择一组真菌毒素进行测试， 这项合作协议是爱荷华州饲料中最受关注的三种：黄曲霉毒素、伏马菌素和 玉米赤霉烯酮将对200个动物饲料样本和100个宠物食品样本进行检测， 霉菌毒素对动物饲料的另一个威胁是有毒元素的污染。金属可能有毒， 非常低的剂量。有毒金属从环境中进入动物食物供应（通过植物和 水），但也可以从与食物直接接触的容器或器具中浸出。他们是非- 这些物质是可生物降解的，难以排泄，导致在组织中蓄积和毒性。金属 在食物链中处于较高位置的动物体内积累量会增加。200个矿物样本将被 重金属测试这些数据将与FDA共享，其结果将塑造未来几年的 这个项目
