Traditional meat inspection important in medium and high risk areas. 14 Potential benefit of serological cysticercosis tests. Classical Meat Hygiene Inspection Risk Assessment of a revised inspection of slaughter animals in areas with low prevalence of Trichinella (EFSA-Q A; March 2005). In consideration of Trichinella-free farms. Importance of surveillance tools in place to detect increases in exposure. Consideration of piglets allowed outdoors before weaning. Feasibility of establishing Trichinella free areas, and if feasible on the risk increase to public health of not examining pigs from those areas for Trichinella spp. (EFSA-Q ; October 2005). Difficultness in establishing of true Trichinella freedom in geographical areas. Health risk associated with the adoption of a visual inspection system in veal calves raised in a Member State (or part of a Member State) considered free of tuberculosis (EFSA-Q ; May, 2006). Importance of surveillance of M. bovis in cattle both for animal and human health reasons. Considerations for the case of integrated production units and in officially 15 bovine tuberculosis-free herds. 34

Difficult to correlate between in-going and residual amounts. Different inhibitory effects depending on product formulation and ph values. Consideration of maximum ingoing amounts. Microbiological criteria and targets based on risk analysis (EFSA-Q ; March 2007). Self-tasking aiming to provide overview of different concepts and their use with special considerations to the applicability of microbiological criteria and targets in the food chain. Public consultation. Usefulness of microbiological criteria for validation and verification of HACCP-based processes. Food Safety Criteria and Process Hygiene Criteria. 17 Integrating risk assessment in legislation Nitrates and Nitrites February 1995 Council Directive 95/2/EC on food additives other than colours and sweeteners. July 2003 EC question to EFSA: (1) Correlation between in-going and residual amounts of nitrites and nitrates, (2) effect of the in-going and residual amount of nitrites and nitrates on the microbiological safety of meat products, in particular related to C botulinum and (3) lowest level of in-going or residual amount of nitrite and nitrates with protective effect?

The BIOHAZ Panel deals with questions on biological hazards (including TSE agents) relating to Food Safety and Food-borne Diseases. The BIOHAZ Panel work in the field of meat hygiene falls within distinct areas, ranging from classical meat hygiene inspection, to microbiological issues and to the review of SRM related issues. EFSA s scientifically based risk assessments serve as a means for the identification of food safety risk control options, which are then reflected in EU legislation. 23 EFSA is committed to independency and transparency luis.vivas-alegre@efsa.europa.eu 24 37
