Under a recent U.S. Food and Drug Administration (FDA) standard for food contaminants, 3.5 ounces of tomato sauce can have up to 30 fly eggs, and 11 ounces of wheat flour can contain 450 insect fragments. How could statistical sampling be used to see that these standards of food hygiene are being met by producers? Sampling allows the FDA to guarantee that 100 percent of all tomato sauce produced is meeting the standard. Sampling allows the FDA to state, within a margin of error and some level of confidence, that tomato sauce produced in the United States is meeting the standard.
