Food allergies are a growing concern for both consumers and producers. In food production, even tiny traces of allergens can cause major health risks, product recalls, and brand damage. While surface cleaning and ingredient control are essential, air quality is often overlooked, yet it’s a critical part of effective allergen control.

Airborne allergens can silently spread throughout a production facility, contaminating products, equipment, and even staff areas. Ignoring air quality can lead to cross-contamination, operational disruption, and regulatory non-compliance. Facilities that prioritise air quality management and LEV system maintenance create safer environments, protect their brand, and ensure consistent product integrity.

Airborne Allergens: The Hidden Hazard

Airborne allergens such as flour, nuts, milk powders, and spices can easily become suspended in the air during mixing, tipping, packing, or cleaning processes. These particles can:

• Settle on surfaces and products

• Cross-contaminate other production lines

• Linger in the air and ductwork for extended periods

Because airborne allergens are invisible, traditional cleaning methods often fail to eliminate them. This makes airborne allergen management a critical part of overall allergen control strategies. Without proper intervention, even a small amount of allergen can contaminate an entire batch of products, risking consumer health and causing brand damage.

Why LEV Systems Matter

Local Exhaust Ventilation (LEV) systems are designed to capture airborne allergens at the point of origin, preventing them from spreading across the facility. Effective LEV systems support food safety compliance and protect both products and staff.

Key benefits include:

• Reducing cross-contamination risk

• Protecting sensitive products and customers

• Supporting audits and regulatory compliance

Proper LEV system maintenance ensures that filters, extraction arms, and ductwork remain fully operational, maximising allergen removal efficiency. Facilities that maintain their LEV systems consistently reduce contamination risk, improve air quality, and strengthen their compliance credentials.

How Workplace Safety Management Helps

Professional support from Workplace Safety Management ensures facilities maintain optimal air quality and effective allergen control. Services include:

• Custom LEV System Design: Systems tailored to the facility’s production lines for maximum allergen capture

• Routine Maintenance and Filter Changes: Ensuring the system continues to remove airborne allergens effectively

• COSHH-Compliant Testing and Documentation: Maintaining regulatory compliance and audit readiness

• Spare Parts Supply: Supporting all major brands to minimise downtime and maintain operational continuity

By partnering with experts, facilities can safeguard employees, maintain airborne allergen management, and protect product integrity.

Air Quality Management: Beyond LEV Systems

While LEV systems form the core of allergen control, a comprehensive air quality strategy also includes:

• Continuous Monitoring: Detecting airborne allergens in real-time to ensure clean production areas

• Ductwork Cleaning: Removing accumulated particles to prevent recirculation

• Staff Training: Educating employees on allergen handling and contamination prevention

• Process Optimisation: Implementing workflow changes to reduce allergen spread

Combining air quality management with LEV system maintenance ensures a facility remains safe, compliant, and productive.

The Business Impact of Allergen Control

Air quality management and allergen control provide clear operational and financial advantages:

• Reduced Recalls: Minimising contamination events protects the brand and prevents costly recalls

• Improved Employee Health: Cleaner air reduces exposure to allergens, decreasing absenteeism and improving productivity

• Regulatory Compliance: Meeting food safety compliance standards avoids fines and operational disruptions

• Enhanced Consumer Trust: Maintaining high safety standards reinforces brand credibility and loyalty

Investing in allergen control demonstrates a commitment to operational excellence and employee safety, while protecting consumers and strengthening your brand reputation.

Maintaining LEV Systems for Long-Term Protection

Routine LEV system maintenance is crucial for sustained allergen control. Maintenance actions include:

• Replacing and inspecting filters regularly

• Checking ductwork for blockages or contamination

• Ensuring extraction arms and airflow remain efficient

• Keeping records for audits and compliance

By maintaining systems proactively, facilities enhance airborne allergen management, reduce unplanned downtime, and ensure consistent compliance with food safety standards.

Planning for High-Volume Production

During peak production, airborne allergens can spread faster and present increased contamination risks. Scheduling LEV audits and air quality management reviews ahead of busy periods ensures that:

• Potential system failures are addressed before they disrupt operations

• Extraction and airflow are at optimal levels

• Staff and products remain protected from allergens

• Compliance is consistently maintained

Proactive planning allows facilities to maintain efficiency and prevent contamination, creating a safer, more productive environment.
