Abstract : Campylobacter is a leading cause of foodborne bacterial enteritis in humans. Consumption or mishandling of
contaminated poultry products are one of the most significant sources of Campylobacter infection in humans. A reduction in
intestinal Campylobacter counts in preharvest poultry would reduce the likelihood of producing contaminated poultry
products, which could drastically reduce the incidence of human illness caused by this pathogen. This study evaluated the
efficacy of in-feed supplementation of two generally recognized as safe (GRAS) compounds, eugenol (a clove extract) and
trans-cinnamaldehyde (an extract of cinnamon), for their ability to reduce enteric colonization of Campylobacter in broiler
chickens. In three replicated trials, day of hatch chicks (N=90 birds/trial) were allocated into nine treatment groups and
received either 0% or 0.1%, 0.2%, 0.4%, 0.8% eugenol or trans-cinnamaldehyde in feed for 14 days prior to necropsy (n=10
birds/treatment). Chicks were challenged in all trials with C. jejuni 72 h after the start of experiment and ceca were collected
on day 14 for enumeration of cecal Campylobacter counts. Enteric Campylobacter counts were reduced for 0.1%, 0.2% and
0.4% eugenol or 0.4% trans-cinnamaldehyde treatment groups in 2 out of 3 trials when compared to the positive controls.
Although these treatments demonstrated some efficacy, they did not consistently reduce cecal Campylobacter in all three
trials.
