Argument: 新黄金80: AA-139

139. The following appeared as part of an article in a trade magazine.
“During a recent trial period in which government inspections at selected meat-processing plants were more frequent, the amount of bacteria in samples of processed chicken decreased by 50 percent on average from the previous year’s level. These results indicate that the trial schedule should be made permanent: by continuing with more frequent inspections, the government could thus cut in half the incidence of stomach and intestinal infections throughout the country. In the meantime, consumers of Excel Meats should be safe from infection because Excel’s main processing plant has shown more improvement in eliminating bacterial contamination than any other plant cited in the government report.”
