This demonstrates the importance of proactive monitoring and appropriate responses to maintain high sanitation standards.

Cleaning and sanitizing harvesting equipment is crucial for preventing contamination and ensuring the safety of the final strawberry product. The process typically involves a two-step approach: cleaning followed by sanitizing.

Cleaning involves removing visible soil, debris, and residues from the equipment using water and a detergent. This is best done immediately after use, while the soil is still wet. We use high-pressure washers with appropriate nozzles to effectively remove debris from hard-to-reach areas. For delicate parts, manual cleaning with brushes and appropriate detergents might be necessary.

Sanitizing follows cleaning and aims to kill or reduce the number of microorganisms. This usually involves rinsing the equipment with a sanitizing solution, such as a chlorine-based solution or a peracetic acid solution (PAA), according to label instructions and regulatory guidelines. Contact time, the duration the equipment is exposed to the sanitizer, is critical and must be followed meticulously. After sanitizing, thorough rinsing with potable water is necessary to remove any sanitizer residue before the equipment is used again.

For example, our berry picking containers undergo a rigorous cleaning process, followed by a dip in a chlorine-based sanitizer before being returned to the fields. Our harvesting equipment, like tractors and conveyors, are cleaned using high-pressure washers and then sanitized with a PAA solution.

Preventing cross-contamination during strawberry processing is paramount. This involves meticulous attention to hygiene at every stage, from the field to the packaging line. We employ a number of strategies:

• Dedicated Equipment: Using separate equipment for different stages of processing minimizes the risk of transferring contaminants. For example, we have dedicated equipment for washing, sorting, and slicing strawberries.
• Sanitation Zones: Establishing separate zones for raw and processed strawberries ensures directional workflow and prevents backflow of contamination. We might have a cleaning zone followed by a pre-processing zone and then a processing zone.
