Talking to media persons during his brief visit to the Kerala Veterinary and Animal Sciences University (KVASU) headquarters here, Dr. Kumar said the United States Drug Administration recommended the production of food products using methods that preserved the environment and avoided synthetic materials, including pesticides and antibiotics.
The U.S., Germany and France were the emerging markets for organic products. Food safety was emerging as the major component of sustainable organic agriculture and the World Health Organisation (WHO) listed the major concerns on food safety as microbiological hazards such as salmonellosis and chemical toxins such as aflatoxins, he said.
“Nearly 2.2 million people are killed annually worldwide, including nearly 3,000 deaths in the U.S., due to salmonellosis, Dr. Kumar said.
Interventions for improving food safety were required at pre-harvest, post-harvest and consumer level to tackle it. Identification of treatments and practices that maintain and improve animal health and food safety without jeopardising the organic standards had been made critical for the progress of the organic livestock industry, he added. 
Plant-Derived Antimicrobials (PDAs) such as phytophenolics were regarded as safe, food grade and bio degradable with plant defence mechanism, he said.
