BACTERIAL BUILDUP: Unsanitized surfaces harbor millions of bacteria within hours. Cross-contamination affects all food prepared on surface. Major cause of multi-victim outbreaks. Cutting boards can contain 200x more bacteria than toilet seats.

Clean and sanitize ALL food contact surfaces: After each use, Between different food types, Every 4 hours in continuous use, When contaminated. Use proper concentration sanitizer (50-100ppm chlorine, 200-400ppm quat). Air dry. Test sanitizer every 2 hours.

SEVERE BIOHAZARD: Rats carry 35+ diseases including Leptospirosis (kidney/liver failure), Hantavirus (38% mortality), Salmonella, and plague. One rat produces 40-50 droppings daily containing millions of pathogens. Urine aerosols spread disease throughout facility.

IMMEDIATE ACTION REQUIRED: Close affected areas, Professional extermination within 24 hours, Clean/sanitize with 10% bleach solution, Discard ALL contaminated food, Seal holes over 1/2 inch, Remove food/water sources, Install bait stations, May require closure.

Improper surfaces harbor bacteria in cracks and cannot be properly sanitized

Use stainless steel, approved plastics; no wood except cutting boards; smooth, intact surfaces

DISEASE VECTORS: Roaches carry 33 types of bacteria, 6 parasitic worms, 7 human pathogens. Travel from sewers/garbage to food surfaces. Spread Salmonella, E. coli, Staphylococcus. Trigger severe asthma and allergies. One roach = likely infestation of hundreds.

Immediate elimination required: Professional extermination ASAP, Find and eliminate water sources (roaches need water daily), Seal all cracks/crevices, Deep clean with degreaser, Remove cardboard/clutter, Apply gel baits in non-food areas, Follow-up treatment in 2 weeks.

WIDESPREAD CONTAMINATION: Mice produce 50-75 droppings daily, each containing Salmonella, Hantavirus. One mouse contaminates 10x more food than it eats through droppings and urine. Mouse allergens trigger asthma. Can infest entire facility in weeks.

Eliminate immediately: Clean all droppings with bleach solution, Seal ALL holes over 1/4 inch, Remove nesting materials, Professional treatment if >10 droppings found, Discard contaminated foods, Install traps/bait stations, Deep clean entire facility.

PEST ATTRACTION: Harborage conditions support pest infestations. Gaps allow entry of rodents carrying 35+ diseases. Standing water breeds flies that spread 100+ pathogens. Clutter provides nesting for pests. Creates ongoing contamination risk.

Eliminate ALL harborage conditions: Seal cracks/holes (1/4 inch for mice, 1/2 inch for rats), Fix leaking pipes, Remove clutter/unused equipment, Eliminate standing water, Clean grease accumulation, Maintain 6 inches clearance from walls, Remove cardboard storage.

WATER CONTAMINATION: Backflow can siphon sewage into water supply, contaminating entire facility. Cross-connections spread pathogens throughout plumbing. Sewage backups create immediate health hazard. Can affect hundreds through contaminated water.

Install backflow preventers on ALL required fixtures. Maintain air gaps (2x pipe diameter minimum). Fix all leaks immediately. Ensure proper drainage - no standing water. Regular plumbing inspection. No direct connections between sewage and water supply.
