    Notizen: : In the past, deliberate contamination of foods in the U.S. has been committed by individual criminals, disgruntled employees, or political activists with a narrow agenda. After September 11, 2001, every nation has had to consider a much wider range of food security issues. Food is a global commodity and nearly every country both exports and imports foods. Every nation must consider the security of its domestic production and look beyond its borders to its trading partners to assure the safety of its food supply. In the nearly 2 years since September 11, 2001, many steps have been taken to improve food security. New legislation has been enacted to strengthen the ability of government to respond to terrorist threats. New relationships have been forged between food security agencies, law enforcement, and the intelligence community. Virtually every segment of the domestic and imported food supply has come under scrutiny in an effort to identify points of weakness and appropriate protective measures. Gaps in our knowledge about specific agents and food processes have been identified and research to fill these gaps has been initiated. This effort will continue for the foreseeable future and could have a wide range of benefits, including improvements to food safety, a reduction in product counterfeiting, and a reduction in the “gray market” food trade. The scale and diversity of the U.S. food supply makes it an attractive target, but at the same time makes it very resilient and responsive to emerging threats.

    Notizen: Characteristics are presented for Yersiniu enterocoliticu-like organisms isolated from vacuum-packaged beef and lamb stored for 21-35 days at l-3°C. Isolation of this organism was more frequent after 28 days of storage under vacuum conditions than under nonvacuum conditions (leaker packages). A higher incidence of isolates was obtained from cuts packaged under high vacuum conditions.

    Notizen: A comparison of three relatively rapid methods of determining free fatty acids concentrations in cheese was performed by correlating the results with a more laborious but accurate gas chromatographic (GC) technique. Acid Degree Values were found to correlate poorly with the GC data, particularly for short chain fatty acids. Values obtained using a Copper Soap Method correlated closely with the GC data for total and long chain fatty acids, but did not correlate as well with short chain fatty acids levels. The Extraction-Titration Method was found to be a simple and reliable technique that yielded values which correlate closely with short chain fatty acid concentrations.

    Notizen: A qualitative screening revealed the occurrence of lipase, esterase, protease, amylase, endo-1,4-β-D-glucanase, xylanase, pectinmethylesterase, polygalacturonase, catalase, β-D-glucosidase and β-D-galactosidase activities in the technical Aspergillus niger enzyme under study (Lipase 2212 D, Röhm). The isolation and purification of lipolytic activities were performed by combination of DEAE-Trisacryl M ion exchange chromatography, Sephadex G 50 gel filtration and hydrophobic chromatography using Phenylsepharose CL-4B. The individual purification steps were checked by specific enzyme visualization in ultrathin agar gels after ultrathin-layer isoelectric focusing (UIEF). Two UIEF homogeneous lipase isoenzymes (I and II) were isolated and characterized by the following parameters: isoelectric points (I: 4.0; II. 3.5); molecular weights (I: 31000 daltons; II: 19000 daltons); carbohydrate contents (I: 6%; II: 9%) and compositions; pH optima (I, II: 5-6); substrate specificities and various effectors.

    Notizen: Yersinia enterocolitica counts of inoculated beef and pork as determined from confirmed isolates picked from trypticase soy agar plates were similar to the counts of confirmed enamel-black colonies on bismuth sulfite agar plates. With three strains of Y. enterocolitica increases in count occurred on raw beef held over a 10-day period at 0–1°C. When inoculated raw or cooked beef and pork were stored at 7°C (0–10 days) or at 25°C (0–24 hr) large increases in Y. enterocolitica count occurred. At 25°C the increases in Y. enterocolitica counts were somewhat greater on cooked than on raw products. These differences in count may have been caused by (a) differences in the physicochemical characteristics of the meat (raw vs cooked) and/or (b) differences in the level and type of microbial flora that developed on these products. In addition to Y. enterocolitica, Staphylococcus and Micrococcus spp. often were dominant on cooked products, Pseudomonas and Microbacterium spp. on raw meats.
