Drying broiler transport cages reduces Campylobacter

Drying broiler chicken transport cages with an absorbent cornstarch powder after spray washing reduces the foodborne pathogen Campylobacter.

Broiler transport cage drying and the application of a dry treatment (absorbent cornstarch powder) have been shown in poultry research to diminish the foodborne pathogen Campylobacter on transport cages.

The objective of this analysis is to evaluate drying time as a means of reducing or eliminating the foodborne pathogen Campylobacter from 5x5 cm squares of fiberglass flooring from transport cages that were intentionally contaminated with 1g of Campylobacter-positive broiler gut contents. 

Campylobacter organisms are sensitive to dry stress. Allowing feces left on transport cage flooring to dry during extended periods of nonuse would be an effective method to reduce or in 24 hours, eliminate, viable Campylobacter left by positive flocks.

The problem with relying on extended periods of nonuse is that poultry processors do not have the time, space or resources to maintain several times the minimum required number of transport cages. The current design of transport dump cages commonly used in the United States does not lend itself to removal and replacement of the floor for separate washing or drying.

Therefore, it was hypothesized that a technique to reduce the amount of time required to dry fecal matter and apply stress to Campylobacter on broiler chicken transport cages may be helpful.

In another trial, combining spray washing and cornstarch application for 15 minutes decreased Campylobacter as much as four hours of drying time.

The findings suggest that washing followed by an absorbent powder could be helpful to aid in the desiccation-caused death of the foodborne pathogen Campylobacter on broiler chicken transport cage flooring should a short turnaround time be necessary.
