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.

Better Campylobacter detection needed to protect chicks

Furthering understanding of Campylobacter ecology in poultry – and protecting young chicks from the bacteria – will require better cultivation and detection methods.
Campylobacter cultivation and detection methods to recover injured or stressed cells need to be greatly improved to allow for the development and implementation of more effective intervention strategies. Poultry scientists should question laboratory results and adopt new methods in order to obtain a better understanding of this elusive organism.

Isolation of Campylobacter from the circulating blood of broilers

From a poultry processing viewpoint, Campylobacter presence in circulating blood of market-age broilers may increase the likelihood of cross-contamination between birds during slaughter.

Comparison of US and EU Salmonella detection methods

Salmonella prevalence on broiler carcasses in the US and the EU and other parts of the world is measured by differing methods. Are the results comparable?
Methods to sample processed broiler carcasses for the presence of Salmonella can differ among countries. Neck-skin excision and whole-carcass rinsing are differing methods used to detect Salmonella prevalence on commercial broiler carcasses before and after chilling.

Salmonella prevalence in poultry varies greatly in emerging markets

Salmonella on raw chicken meat at the retail level varied greatly among emerging poultry market countries in this analysis.
Globalization of the food supply can impact food safety from both a public health and international trade perspective, but insufficient data exist to develop internationally recognized standards. The presence of Salmonella on poultry is an important factor in protecting public health and facilitating trade.

Zero Salmonella tolerance on poultry: Worthy goal or trade protectionism?

Can an importing country justify, on purely scientific grounds, a zero-tolerance policy for Salmonella on raw poultry?
Can an importing country justify on purely scientific grounds a zero-tolerance policy for Salmonella on raw poultry? The term “zero tolerance” for specific pathogens such as Salmonella in raw food products is interpreted differently in different countries and therefore has been confusing, misleading and misapplied. Using terms such as “zero tolerance” or “absence of a bacterium” in relation to raw poultry should be avoided unless these terms are specifically defined and explained by international agreement.

Efecto de las yemas no absorbidas en pollos de engorda sobre la inocuidad alimentaria

Las yemas de huevo no absorbidas y su contenido bacteriológico pueden tener un importante impacto sobre la inocuidad alimentaria en pollos de engorda.
El principal suministro de energía para el embrión aviar en desarrollo es la yema, que contiene carbohidratos, lípidos y proteínas, de los cuales son los lípidos la fuente más importante de energía para dicho organismo. Las yemas de huevo no absorbidas y su contenido bacteriológico pueden tener un importante impacto sobre la inocuidad alimentaria en pollos de engorda.

Food safety effects of unabsorbed yolks in broilers

Unabsorbed egg yolks and their bacteriology can have an important impact on food safety in broilers.
The main energy supply for the developing avian embryo is yolk, which contains carbohydrates, lipids and proteins, with lipids providing the most important source of energy to the embryo. Near the end of the incubation period, the yolk sac is internalized into the abdominal cavity and at the time of hatch, the remaining yolk comprises approximately 20% of the chick’s body weight and continues to provide immediate posthatch energy, protein and water for nourishment.
