As discussed in the FDA's June 2006 guidance document, "Recommendations for the Early Food Safety Evaluation of New Non-Pesticidal Proteins Produced by New Plant Varieties Intended for Food Use" (available at http://www.cfsan.fda.gov/~dms/bioprgu2.html), in cases where a new plant variety intended for food use may be present in the food supply at only low levels, FDA believes that any food or feed safety concern is limited to the safety of the new protein (such as its potential toxicity or its potential to be allergenic). If a protein has previously been evaluated as part of a biotechnology or early food safety consultation and no safety concerns were identified, FDA would not have safety concerns about the low level presence in food or feed of a new plant variety containing that protein.

FDA的意思很明显，如果转入的基因所表达的蛋白没有毒性，ＦＤＡ不认为这些基因所表达的微量蛋白会有（食品）安全问题。
