As A Grower, How Can You Make Fruits and Vegetables Safer For Your Consumer

Introduction OSU Food Safety Team created in 2007 to address rising food safety concerns in Ohio. Grant received to educate fruit and vegetable growers in Ohio producing a commodity for sale to the public. The objective of OSU Food Safety Team is combine critical food safety knowledge and real world tools into action on your farm to protect you and your customers.

Water: The Critical Control Point?

Water Management Know the source of the water and intended use. Evaluate the irrigation method. Test water quarterly for fecal coliforms and keep records of all water test results. Be active in local watershed groups.

Manure and Soil Amendments

Manure = Fecal Matter = Microbes Human or animal: DO EVERYTHING you can to keep manure off produce. Preventing contamination is THE goal.

Worker Hygiene

Farm Worker Hygiene Provide clean restrooms with soap, water, and single-use towels. Teach workers about food safety and their role in preventing microbial contamination of fresh fruits and vegetables. Enforce proper use of facilities.

Provide clean restrooms with soap, water, and single-use towels.

Teach workers about food safety and their role in preventing microbial contamination of fresh fruits and vegetables.

Enforce proper use of facilities.

Is worker training really a priority? Farm workers are sometimes the last/only people to handle the produce before the consumer. Workers are capable of learning about food safety issues. Effective training results in better employees and safer produce.

Harvest Considerations Ideally pick dry fruit or vegetable. Leave fruit that has bird droppings on it. Clean and sanitize totes daily. Cool product quickly. Teach workers about proper handwashing.

Ideally pick dry fruit or vegetable.

Leave fruit that has bird droppings on it.

Clean and sanitize totes daily.

Cool product quickly.

Teach workers about proper handwashing.

Avoid Introducing Pathogens to your Harvest Do Not Harvest Dropped Fruit. Heavily Bruised, Punctured or Decaying Fruit should not be used for fresh market or processing.

Do Not Harvest Dropped Fruit.

Heavily Bruised, Punctured or Decaying Fruit should not be used for fresh market

or processing.

Movement of equipment and workers Traffic patterns for employees and equipment should be established to avoid cross contamination between raw manure and compost or crops

Field conditions may increase risks

Growers Are Innovating Their Own On-Farm Sanitation Routines

Promote Cleanliness at U Pick Invite customers to wash their hands prior to entering the fields. Provide clean and convenient restrooms for customer use. Supply soap, clean water, and single -use towels for hand washing.
