Ensure safe strawberry handling with 0–300 ppm chlorine test strips. Verify sanitizer levels in dump tanks and flumes to prevent E. coli, Salmonella, and Listeria contamination. Essential for growers, packers, HACCP coordinators, and food safety auditors.

Best Practices for Strawberry Packhouses and Farmers


Strawberries are one of the most delicate fruits in the produce industry, and their short shelf life makes proper handling essential. To reduce the risk of contamination and maintain buyer confidence, both packhouses and growers should follow these best practices:

  • Maintain Effective Wash Water Sanitation
    Use free chlorine at 50–200 ppm in dump tanks or flumes.
    Monitor chlorine frequently and replenish as needed.

  • Test and Control Wash Water pH
    Keep pH in the 6.5–7.5 range to ensure chlorine remains active.
    At higher pH, sanitizer effectiveness drops sharply.

  • Prevent Cross-Contamination
    Replace wash water regularly, especially during heavy throughput.
    Clean and sanitize tanks, flumes, and conveyors daily.

  • Document Food Safety Compliance
    Keep test records of chlorine and pH for audits.
    Align with FSMA Produce Safety Rule and GlobalG.A.P. requirements.

  • Train Harvest and Packing Staff
    Reinforce hand hygiene, glove use, and no-jewelry policies.
    Ensure employees understand why wash water testing matters.

  • Follow Cooling and Storage Protocols
    Rapidly cool fruit to slow spoilage and microbial growth.
    Keep cold chain intact through distribution.

The high chlorine test strips are handy for operators to measure Free Chlorine levels to ensure adequate dosages have been achieved when disinfecting watermains and cleaning storage facilities. They arrived very quickly.

Interesting applications, thanks for the feedback.

I am glad these are packaged in a container; we have had some in the past packaged in a paper envelope (from another company), which is hard to keep dry. They work just as advertised - the only imperfection for us is that the colors are fairly similar and it can be hard to tell at a glance what the result is. Otherwise, great.

Thanks for the feedback. The packaging for most sanitizer test strips come in special desiccant lined containers which is explained further in: Test Strip Expiration Dates; Good Today, Dead Tomorrow?

Some of the color charts are indeed harder to read than others. Good lighting can help. Fluorescent lighting is not as contrast friendly as natural sunlight or halogen or quartz.
