Field Experiences: Conducting One Health Surveys to Determine Transmission Risks from Poultry in Markets and Farms in Southern India.

The One Health Poultry Hub conducted multiple work packages on poultry intensification and risk, including a study on Campylobacter and nontyphoidal Salmonella infections among retail chicken shop workers in India. Here, we highlight the experience of administering questionnaires and collecting stool and blood samples from these workers and chickens in multiple cities in Tamil Nadu state. The significant challenges noted were as follows: (i) selecting and locating shops, (ii) obtaining consent and collecting samples, and (iii) timely transport of samples to the laboratory. Similar challenges may be faced in One Health studies in poultry and other animal health sectors in low-resource settings.
