Accessibility Review

Accessibility for educational games is a work in progress across the industry. We continually seek solutions to make our products fully accessible, and we strive to adhere to established standards for accessibility and usability on each new project. Some of our older products may not be accessible in all areas and have not been optimized for current accessibility recommendations. Here, we offer the content and approach of this game, so that learners are better able to find alternative content and ways of learning.

Cleaning and Sanitizing Farm Tools and Equipment

Cleaning and Sanitizing Farm Tools and Equipment features an introductory animation and three interactive modules that explore best practices for cleaning and sanitizing food contact surfaces on farms, including tools and equipment, to protect against the contamination of produce.

It is intended to be completed in the following order: Introductory animation, Introductory interactive, Test Strip Lab, Titration Lab. Users will learn the basic steps of cleaning and sanitizing, how to choose a sanitizer, and why monitoring is important (Introduction). They will then learn about using test trips to monitor chlorine levels of chlorine sanitizer (Test Strip Lab). They will then learn a different and more precise way of monitoring sanitizer levels, for example peroxyacetic acid (Titration Lab).
