The National Advisory Committee on Microbiological Criteria for Foods (NACMCF) is holding a public meeting on September 17-20. The committee will discuss Salmonella performance standards for meat and poultry products; Escherichia coli 0157:H7 in blade-tenderised, non-intact beef; and will review the Codex Alimentarius Commission's Draft Guidelines for the Validation of Food Hygiene Control Measures. The committee will also start a scientific assessment on the appropriate warming temperatures for controlling pathogens and toxins and introduce the scientific basis for establishing safety-based "use by" date labelling for refrigerated, ready-to-eat foods. The full committee will meet on Monday, September 17 and subcommittee meetings will be held on Sept. 18-19 at the Capital Hilton, 1001 16th & K Street, NW, Washington, DC 20005. All meetings will run 8:30 a.m. to 5 p.m. and will conclude with a plenary session on Sept. 20. The NACMCF provides scientific advice and recommendations to the Secretary of Agriculture and the Secretary of Health and Human Services on public health issues relative to the safety and wholesomeness of the U.S. food supply, including development of microbiological criteria and review and evaluation of epidemiological and risk assessment data and methodologies for assessing microbiological hazards in foods. The committee also provides advice to the Departments of Commerce and Defense.
