Risk evaluation and management to reaching a suggested FSO in a steam meal

Area of Science:

• Food safety microbiology
• Quantitative risk assessment
• Microbial modeling

Background:

• Steam meals, like Chicken Tandoori, are ready-to-eat products requiring thorough microbial safety evaluation.
• Identifying key foodborne pathogens is crucial for ensuring consumer safety in microwave-heated meals.

Purpose of the Study:

• To identify and quantify microbial risks in Chicken Tandoori steam meals.
• To compare predictive microbial modeling with experimental challenge tests.
• To establish risk management strategies through Performance Objectives and Food Safety Objectives.

Main Methods:

• Risk assessment using Risk Ranger® to identify Listeria monocytogenes, Salmonella Typhimurium, and Bacillus cereus.
• Quantitative microbiology employing predictive models (gamma model, ComBase program®).
• Verification through growth and inactivation challenge tests.

Main Results:

• The gamma model and ComBase program® provided comparable predictions for microbial behavior.
• Challenge tests revealed some discrepancies compared to model predictions, highlighting the need for experimental validation.
• Identified critical control points for managing pathogen risks throughout the food chain.

Conclusions:

• Predictive models are valuable tools but require validation with experimental data for steam meals.
• Establishing clear Performance Objectives and Food Safety Objectives is essential for effective risk management.
• This research provides a framework for ensuring the safety of Indian-style steam meals.
