Cotton extraneous matter (EM) and special conditions are the only cotton quality attributes still determined manually by US Department of Agriculture Agricultural Marketing Service (USDA-AMS) classers. To develop a machine EM classing system, a better understanding of what triggers a classer EM call is needed. The goal of this work was to develop new information about cotton EM, such as bark and grass, and leaf particles, using machine measurements, to aid in the development of instrumentation for cotton quality measurements. AMS classers were tasked in identifying and denoting bark/grass in large-area color images of cotton samples. Image segmentation analysis was applied to detect non-cotton items, such as leaf particles, and the classer denoted bark/grass objects were segmented manually. Further image analysis was used to measure shape and color parameters of these bark/grass objects and leaf particles in the sample images. These measurements of the bark/grass objects and leaf particles were compared and logistical regression analyses conducted to evaluate classification. For every shape and color parameter, there were significant differences between the bark/grass objects and the detected leaf particles in the images. The differences were greater for the shape parameters than for the color parameters. A classification model with shape, color, and log-transformed shape parameters consistently classified the bark/grass objects and leaf particles most accurately with 99.5% and 97.6% correct classification rate, respectively. However, classification models that were 99% correct classifying manually segmented bark/grass were only about 77% correct when applied to the machine detected bark/grass particles.

A survey was made to determine the levels of insect damage and rodent excreta pellets in wheat. The analytical data obtained represented the various grade designations of wheat normally encountered during wheat grade certification in the 34 Agricultural Marketing Service, Grain Division, field offices. The mean and range of weights of insect-damaged kernels per 100 g and rodent excreta pellets and pellet fragments per kilogram were 71.5 mg (0–3809 mg) and 0.9 mg (0–100 mg), respectively. The mean and range of numbers of insect-damaged kernels and rodent excreta pellets were 3.3 (0–169) and 0.1 (0–11), respectively. The percentages of samples containing insect-damaged kernels and rodent excreta were approximately 35 and 7%, respectively.

ABSTRACT The Agricultural Marketing Service procures boneless and ground beef for federal nutrition assistance programs. It tests procured beef for concentrations of standard plate counts (SPCs), coliforms, and Escherichia coli and for the presence of Salmonella and Shiga toxin–producing E. coli. Any lot exceeding predefined critical limits (100,000 CFU g−1 for SPCs, 1,000 CFU g−1 for coliforms, and 500 CFU g−1 for E. coli) or positive for Salmonella or Shiga toxin–producing E. coli is rejected for purchase. Between 1 October 2013 and 31 July 2017, 166,796 boneless beef lots (each approximately 900 kg) and 25,051 ground beef sublots (each approximately 4,500 kg) were produced. Salmonella was detected in 1,955 (1.17%) boneless beef lots and 219 (0.87%) ground beef sublots. Salmonella sample size increased from an individual 25-g sample to a co-enriched 325-g sample on 1 March 2015. Salmonella presence was associated with season (lowest in spring), larger sample size, and increased log SPC in boneless and ground beef. Increased log E. coli was associated with Salmonella presence in boneless beef, but not ground beef. Salmonella Dublin was the most common serotype in boneless beef (743 of 1,407, 52.8%) and ground beef (35 of 171, 20.5%). Salmonella Dublin was generally associated with lower indicator microorganism concentrations compared with other Salmonella serotypes as a group. Relative to other Salmonella, Salmonella Dublin was associated with season (more common in spring) and smaller sample size in boneless and ground beef. Decreased log SPCs and log coliforms were associated with Salmonella Dublin presence in boneless beef, but not in ground beef. Differential associations between Salmonella Dublin and other serotypes with indicator microorganisms were strong enough to cause confounding and suggest that the presence of Salmonella Dublin needs to be accounted for when evaluating indicator performance to assess Salmonella risk in boneless and ground beef.

AbstractMeat goat producers were queried to determine subjective estimates of premiums they would receive for slaughter kids of various selection classes. Market-based predicted premium estimates were obtained via regression using published U.S. Department of Agriculture Agricultural Marketing Service data. Subjective versus market-based predicted premium estimates were compared to determine producer accuracy in predicting premiums. Producers tended to overestimate quality premiums. Producers more accurate in their estimates tended to be larger-scale and older and to hold college degrees, sell more slaughter goats via auction, and manage their goats more intensively. Results contribute to the literature on producer accuracy in predicting prices.

Abstract A video image analysis system was designed to quantitatively measure the amount of specks and the color of peanut butter samples for grade purposes. The video image of a peanut butter surface 5.8 cm by 5.8 cm was captured and converted into 384 by 384 picture elements (pixels). The intensity of each of the 147,456 pixels was classified into one of 256 shades of gray from zero for black to 255 for white. The percent of total pixels that represented specks was defined as the speck index. The aveage shade of gray of all 147,456 pixels was defined as the color index. The speck and color indices were computed for 52 peanut butter samples that had been graded by experienced Agricultural Marketing Service (AMS) inspectors. The speck and color indices were both in good agreement with the AMS speck and color classifications assigned to the samples by the AMS inspectors.

AbstractHedonic modeling of Oklahoma cow auction data is used to determine the market value of bred cow characteristics. We use Agricultural Marketing Service data that let us consider more years and more lots of cattle than is typical for a cattle hedonic study. The greatest price premiums were for black, late-gestating cows, categorized as high quality by market reporters and weighing between 1,600 and 1,700 lb. Previous research on optimal cow size finds much smaller-size cows are optimal, and our research finds that larger cows receive a lower price per pound but still receive a substantially higher price per head.

AbstractThin markets create challenges for reporting market information by the U.S. Department of Agriculture (USDA) and for users of the information. This study examines distributions of transactions comprising daily price reports in the U.S. hog market. We determine publicly reported daily prices are sensitive to which packing plants buy hogs. Transaction prices comprising USDA Agricultural Marketing Service price reports are not normally distributed; care must be taken in reporting and interpreting transaction prices. Economically important variations in prices occur because of packer-specific indicators. Daily reported prices are used as base prices in marketing agreements, making variation of even greater importance.

Abstract A total of 291 hard red winter wheat samples, 286 hard red spring wheat samples, and 271 soft red winter wheat samples were analyzed for the presence of ochratoxin and aflatoxin. Samples in all grades came from those collected during crop years 1970–1973 for grade determinations by the Agricultural Marketing Service, U.S. Department of Agriculture. Sensitivity limits of the analytical method as carried out were 1–3 ppb aflatoxin B1 and 15–30 ppb ochratoxin A. No aflatoxin was detected in any sample. Three samples of hard red winter wheat (Grades U.S. No. 4 and 5 and Sample Grade) contained ochratoxin A (trace, 35, and 25 ppb, respectively). Eight of the hard red spring wheats contained ochratoxin A (15-115 ppb); these were in Grades U.S. No. 4 and 5 and Sample Grade.
