Guide to Minimize Microbial Food Safety Hazards for Fresh

Fruits and Vegetables

(The Guide)

The Guide

• Broadscope - practices common to the growing and packing of most fresh produce

• Guidance only - no new requirements

• Risk reduction, not elimination

Fresh Produce

Scope:

• Fruits and vegetables likely to be sold in an unprocessed or minimally processed (raw) form

• Likely to be consumed without a microbiologically lethal treatment

• Maybe intact or cut during harvest

• Includes “fresh-cut” and other specialty products

Use Of The Guide

• Increase awareness of common microbial hazards for fresh produce

• Useful when practices recommended to minimize hazards are adapted to specific operations- Assess individual operations

- Institute appropriate cost effective practices

• Water

• Manure and Municipal Biosolids

• Worker Health and Hygiene

• Sanitary Facilities

• Field/Packing Facility Sanitation

• Transportation

• Traceback

Water

• Water quality dictates the potential for contamination

– May be a direct source of contamination or

– May spread pathogens in the field or packinghouse

• Surviving pathogens on produce may cause illness

Water Quality

Needs vary with how and when water is used

• Degree of contact• Time until harvest• Crop characteristics

Processing Water

• “Safe and Sanitary” meets microbiological standards for drinking water

• If water is recycled, follow GMPs to maintain water quality

• Water use should not contribute to food safety concerns

Consider Antimicrobials

Useful in processing water for

• Reducing pathogens on the surface of produce and

• Reducing build-up of pathogens in processing water

Manure and Biosolids

• Beneficial fertilizer and soil amendment

• Significant potential source of human pathogens

– E. coli O157:H7

– Salmonella– Cryptosporidium

Manure and Biosolids

Growers should follow GAPs for handling animal manure or biosolids to minimize microbial hazards

Manure

GAPs to minimize microbial hazards

• Treatments to reduce pathogens

• Maximize time between application and harvest

Personal Health and Hygiene

• Establish a worker training program– Teach basic sanitation and hygiene – Follow-up sessions may be needed

• Become familiar with disease signs and symptoms

• Provide protection from lesions

Field Sanitation

• Keep harvest and packing equipment as clean as practicable

• Keep harvest containers clean

• Assign responsibility for equipment to person in charge

Packing Facility Sanitation

• Keep equipment as clean as practicable

• Clean packing areas at end of each day

• Maintain cooling system in working order

• Clean product storage areas regularly

Pest Control

• Establish a pest control system

• Maintain the grounds in good condition

• Monitor and maintain facilities regularly

• Block access of pests into facility

• Use a pest control log

Accountability

• Once GAPs and GMPs are in place, ensure the process is working

• Comprehensive and coordinated effort throughout production and distribution

• Assign responsibility for specific tasks

• Follow-up on the process

Traceback

The ability to identify the source of a product

• Cannot prevent initial outbreak

• Important compliment to GAPs and GMPs

• Limit economic and public health impact

• Information may help identify/eliminate hazards
