Pollinator Plant Sale @ Tulsa (Tulsa Zoo)
May 27 @ 9:00 am – 5:00 pm
Pollinator Plant Sale @ Tulsa (Tulsa Zoo) | Tulsa | Oklahoma | United States

Visit the Tulsa Zoo’s Pollinator Plant Sale every Saturday and Sunday in May at the zoo’s gift shop, Meerkat Market. You can purchase various plant species for your garden at home, so you can attract pollinator species. Pollinators, such as butterflies, hummingbirds, bees, are extremely important to the well-being of many plants and crops, so it’s important to provide them with necessary resources.


All plants are in pots and will be sold for $3.50 each (member and employee discounts do not apply). A specific quantity of each plant will be available for sale each weekend and when that quantity is sold there will be no more available until the next weekend. Plants will not be held for customers during their visit to the zoo. All plants may be planted in full sun locations and almost all require very little watering after becoming established.

Produce Safety Alliance Grower Training Course @ Pawnee (Pawnee Nation College)
Jun 8 @ 8:30 am – 5:00 pm
Produce Safety Alliance Grower Training Course @ Pawnee (Pawnee Nation College) | Pawnee | Oklahoma | United States

Who Should Attend

Fruit and vegetable growers and others interested in learning about produce safety, the Food Safety Modernization Act (FSMA) Produce Safety Rule, Good Agricultural Practices (GAPs), and co-management of natural resources and food safety. The PSA Grower Training Course is one way to satisfy the FSMA Produce Safety Rule requirement outlined in § 112.22(c) that requires ‘At least one supervisor or responsible party for your farm must have successfully completed food safety training at least equivalent to that received under standardized curriculum recognized as adequate by the Food and Drug Administration.’

What to Expect at the PSA Grower Training Course

The trainers will spend approximately seven hours of instruction time covering content contained in these seven modules:

  • Introduction to Produce Safety
  • Worker Health, Hygiene, and Training
  • Soil Amendments
  • Wildlife, Domesticated Animals, and Land Use
  • Agricultural Water (Part I: Production Water; Part II: Postharvest Water)
  • Postharvest Handling and Sanitation
  • How to Develop a Farm Food Safety Plan

In addition to learning about produce safety best practices, key parts of the FSMA Produce Safety Rule requirements are outlined within each module. There will be time for questions and discussion, so participants should come prepared to share their experiences and produce safety questions.

Benefits of Attending the Course

The course will provide a foundation of Good Agricultural Practices (GAPs) and co-management information, FSMA Produce Safety Rule requirements, and details on how to develop a farm food safety plan. Individuals who participate in this course are expected to gain a basic understanding of:

  • Microorganisms relevant to produce safety and where they may be found on the farm
  • How to identify microbial risks, practices that reduce risks, and how to begin implementing produce safety practices on the farm
  • Parts of a farm food safety plan and how to begin writing one
  • Requirements in the FSMA Produce Safety Rule and how to meet them.

After attending the entire course, participants will be eligible to receive a certificate from the Association of Food and Drug Officials (AFDO) that verifies they have completed the training course. To receive an AFDO certificate, a participant must be present for the entire training and submit the appropriate paperwork to their trainer at the end of the course.
