Stung by criticism over recent outbreaks of listeriosis with the Boar’s Head episode as an outstanding example, the USDA Food Safety and Inspection Service (FSIS) has introduced an initiative to reduce foodborne infection due to Listeria.
The multiphase program will include testing for the genus Listeria in addition to a previous concentration on L. monocytogenes, the principal pathogenic species. This approach is based on the fact that if any Listeria is isolated from equipment or the environment of a plant producing ready-to-eat items, deficiencies in structure or operations exist, predisposing to infection.
The FSIS will work closely with the National Advisory Committee on Microbial Criteria for Foods for guidance on procedures and regulations. In 2025 FSIS will intensify assessment of plants and facilities with an emphasis on sanitation. Plants identified as a risk will be subject to repeat visits with the participation of senior inspectors and supervisors.
Instruction and training for food safety inspectors will be intensified. A mandatory training review course on ready-to-eat foods has been issued and will require study and examination to ensure competency by mid-February 2025.
