Pest infestations in food premises are serious health hazards, risking closure by public health authorities due to pathogen contamination. Public health inspectors assess kitchen sanitation, damaged packaging, pest droppings (extent, location, freshness), and contaminated food signs, as pests spread pathogens causing foodborne illness. Mouse excretions carry hantavirus, a potentially fatal respiratory virus that becomes airborne if disturbed, so never sweep or vacuum them. Use the public health-approved method: ventilate by opening windows and doors for 30 minutes, wear gloves, goggles, and a mask, mix a bleach solution (1 part household bleach to 9 parts water), pour over excretions, and let sit for 20 minutes to neutralize pathogens.

Gently wipe with paper towels, double-bag for disposal without squeezing, and ventilate again for 30 minutes. These measures—thorough inspections and safe cleaning practices—block hantavirus and pathogen risks, ensuring a hygienic kitchen and customer safety while meeting public health standards.

You’ll learn about the food safety risks posed by pests and how to safely address pest evidence, particularly mouse excretions, to prevent contamination and health hazards. Let’s dive in!

Pest Infestations: A Health Hazard

Pest infestations in food premises are serious health hazards that can lead to closure by public health authorities:

• Inspection Assessment: If evidence of pests (e.g., droppings, damaged packaging) is found, a public health inspector evaluates:
  • Overall kitchen sanitation.
  • Damage to food packaging.
  • Presence of pest droppings, their extent, location, and freshness.
  • Signs of contaminated food.
• Risk: Pests can contaminate food with pathogens, posing a risk of foodborne illness, and severe infestations may warrant immediate closure.

Safely Cleaning Mouse Excretions

Mouse feces and urine can carry hantavirus, a harmful respiratory virus that can become airborne when disturbed and can be fatal. Never sweep or vacuum mouse excretions to avoid spreading the virus. Follow this public health approved method to clean them safely:

1. Ventilation: Open all windows and doors for 30 minutes before cleaning to ensure good air circulation.
2. Protective Gear: Wear gloves, goggles, and a mask to avoid exposure.
3. Prepare Solution: Mix a strong bleach solution (1 part household bleach to 9 parts water).
4. Apply Solution: Pour the bleach solution over the excretions and let it sit for at least 20 minutes to neutralize pathogens.
5. Clean Up: With protective gear on, gently wipe up excretions with paper towels.
6. Dispose: Double-bag the paper towels and place them in the trash without squeezing the bag closed.
7. Post-Cleaning Ventilation: Keep windows and doors open for an additional 30 minutes after cleaning.

Why This Matters

Pests like mice can contaminate food and surfaces with pathogens, including hantavirus, posing serious health risks. Proper cleaning methods and vigilance during inspections prevent foodborne illness and ensure compliance with public health regulations. Check course resources for more guidance on pest control practices.

Key Takeaways:

• Pest infestations are health hazards that may lead to closure, with inspectors assessing sanitation, packaging damage, and droppings.
• Never sweep or vacuum mouse excretions due to hantavirus risk; use the public health approved method (ventilation, protective gear, bleach solution, careful cleanup).
• Safe pest control protects food safety and prevents severe health risks from contaminated surfaces.
