Food Safety in School Cafeterias: Protecting Our Children’s Health

 

Every year, millions of people fall ill from foodborne illnesses.

Sadly, children are particularly susceptible to these.

A study published in the Journal of School Health highlighted the case of American children aged 5-17 years old, who account for a disproportionate number of foodborne illness cases in the country –  17.7 illnesses per 1,000 people compared to the national average.

These illnesses can range from mild discomfort to severe complications, with the CDC reporting an alarming number of hospitalisations and deaths annually.

The issue of food safety in schools isn’t limited to the United States.

While obtaining specific data from every country can be challenging, the global concern for foodborne illnesses highlights the potential risk in school cafeterias everywhere.

Thankfully, there are effective strategies to prevent these occurrences and safeguard the health of our children.

In this post, we explore food safety risks in schools and the most effective approaches to face them, focusing on Hazard Analysis and Critical Control Points (HACCP) principles.

 

Food Safety in School Cafeterias: Main Risks

Ensuring safe and healthy school lunches requires awareness of potential food safety hazards at every stage of the food handling process.

Here’s a breakdown of some key areas of concern:

1. Improper temperature control

• Danger Zone: Bacteria multiply rapidly at temperatures between 40°F (4°C) and 140°F (60°C), often referred to as the “danger zone.”
• Risk: Improperly cooked or held food within this temperature range can become breeding grounds for harmful bacteria like Salmonella, E. coli, and Staphylococcus aureus, leading to foodborne illness outbreaks.
• Examples: Undercooked meats, reheated leftovers not reaching safe temperatures, improperly stored perishable items.

2. Cross-contamination:

• Raw vs. Cooked: Transferring bacteria from raw ingredients (meat, poultry, eggs) to cooked or ready-to-eat foods can cause illness.
• Improper Handling: Using the same utensils or surfaces for raw and cooked foods without proper cleaning increases the risk.
• Personal Hygiene: Inadequate handwashing by staff can spread bacteria from hands to food.

3. Allergen mismanagement:

• Food Allergies: Schools need to be extra vigilant about managing food allergies among students. Accidental exposure can cause severe reactions.
• Labeling Errors: Improper food labelling or ingredient substitutions can put students with allergies at grave risk.
• Cross-Contact: Similar to bacteria, allergens can transfer from one food to another through shared equipment or surfaces.

4. Perishable food storage:

• Improper Storage: Storing perishable foods at incorrect temperatures can accelerate spoilage and increase the risk of bacterial growth.
• Stock Rotation: Not following FIFO (First In, First Out) principles can lead to outdated food being served.
• Temperature Monitoring: Inadequate temperature monitoring of refrigerators and freezers can lead to undetected spoilage.

5. Inadequate cleaning and sanitation:

• Equipment and Surfaces: Improper cleaning and sanitation of food preparation surfaces, utensils, and equipment can harbor bacteria and increase the risk of contamination.
• Handwashing Facilities: Inadequate access to handwashing facilities or poor handwashing practices by staff can spread germs.
• Disinfection Procedures: Ineffective disinfection procedures for spills or contaminated areas can allow bacteria to persist challenging food safety in schools.

 

 

The Challenge of Volunteer Food Prep

While parent volunteers bring valuable support to schools, their lack of experience in commercial kitchens and food safety protocols can pose a potential risk.

• Limited training: Volunteers might not receive comprehensive training on food safety best practices, including proper hygiene, temperature control, and allergen management.
• Unfamiliarity with regulations: Food safety regulations can be complex, and volunteers might not be aware of specific rules governing school cafeterias.
• Unforeseen errors: Unintentional mistakes due to lack of experience, such as cross-contamination or improper handling procedures, can increase the risk of foodborne illnesses and pose a challenge to food safety in schools.

 

 

Balancing Volunteer Support with Food Safety in Schools:

Schools can mitigate the risks posed by volunteers by implementing the following strategies:

• Mandatory training: Provide mandatory food safety training for all volunteers involved in food preparation. This training should cover hygiene practices, temperature control, allergen management, and proper food handling procedures.
• Clear instructions: Develop clear and concise written instructions for each preparation task. Regularly review these instructions with volunteers.
• Supervision and support: Assign experienced staff to supervise volunteers, answer questions, and ensure adherence to food safety protocols.
• Focus on low-risk tasks: Assign volunteers to tasks that minimize food safety risks, such as portioning pre-cooked items or assembling pre-washed ingredients.

By fostering collaboration between schools, food safety professionals, and parent volunteers, educational institutions can leverage the benefits of volunteer support while prioritising food safety in schools.

 

HACCP: A Systematic Approach to Food Safety in School Canteens

The Hazard Analysis and Critical Control Points (HACCP) system offers a structured and scientific approach to ensuring food safety throughout the entire food handling process.

Here’s how HACCP principles can be applied in school cafeterias to address the challenges earlier mentioned:

1. Conduct a Hazard Analysis:

• Identify all potential biological, chemical, and physical hazards that could contaminate food at each stage, from receiving ingredients to serving meals. Examples include:
  • Biological: Bacteria, viruses, parasites from raw ingredients or improper storage.
  • Chemical: Cleaning chemicals contaminating food preparation surfaces.
  • Physical: Glass shards, foreign objects accidentally getting into food.

 

2. Identify Critical Control Points (CCPs):

• Pinpoint the specific steps in the food handling process where controls can be implemented to prevent, eliminate, or reduce identified hazards to an acceptable level. Here are some CCP examples in school cafeterias:
  • Cooking temperatures: Ensuring meat, poultry, and eggs reach safe internal temperatures to eliminate harmful bacteria.
  • Cooling procedures: Rapidly cooling cooked foods to prevent bacterial growth.
  • Reheating temperatures: Ensuring reheated leftovers reach safe temperatures throughout.
  • Handwashing: Staff following proper handwashing procedures before and during food preparation.
  • Allergen management: Effectively labelling and storing food to prevent allergen cross-contamination.

 

3. Establish CCP Limits:

• Define specific parameters for each CCP to ensure effective hazard control. Examples:
  • Minimum internal temperature for cooked chicken: 165°F (74°C).
  • Maximum time allowed for cooling cooked food to 41°F (5°C).
  • Minimum acceptable chlorine level in cleaning solutions.
    

     

    

 

4. Monitoring Procedures:

• Establish procedures to continuously monitor each CCP and ensure adherence to the established limits. Examples include:
  • Using thermometers to check internal food temperatures during cooking and reheating.
  • Recording temperatures and other CCP data in a logbook.
  • Regularly monitoring handwashing practices and the availability of handwashing supplies.

 

5. Corrective Actions:

• Develop a plan for corrective actions to be taken if a CCP limit is not met. Examples:
  • Rejecting undercooked food or reheating it to the proper temperature.
  • Discarding food stored at unsafe temperatures.
  • Retraining staff on proper handwashing procedures.

 

6. Verification Procedures:

• Implement procedures to verify the effectiveness of the HACCP plan. Examples:
  • Conducting regular internal audits of the HACCP system.
  • Inviting external food safety professionals to conduct inspections.
  • Reviewing and updating the HACCP plan as needed.

 

7. Record Keeping:

• Maintain comprehensive records of all CCP monitoring data, corrective actions taken, and verification activities. These records demonstrate the school’s commitment to food safety and can be helpful during inspections.

By implementing HACCP principles, schools can create a data-driven food safety culture, minimise the risks associated with volunteer involvement, and ultimately, ensure the safety of student lunches.
