Fish farming pictures. Meanwhile, food fraud is rising... "The recent development of high-tech tools -- including DNA testing -- has made it easier to detect fraud that might have gone unnoticed a decade ago. DNA can be extracted from cells of fish and meat and from other foods, such as rice and even coffee. Technicians then identify the species by comparing the DNA to a database of samples. Another tool, isotope ratio analysis, can determine subtle differences between food -- whether a fish was farmed or wild, for example, or whether caviar came from Finland or a U.S. stream." On a related note, a study recently revealed that food portions in artistic depictions of the Last Supper have become larger and larger over the years.
