讲座主题:
the market for private food safety certifications:development, conceptual framework, and some empiricalevidence on whether they made our food system safer
讲座摘要：
since the inception of private food safety standards in the late 1990s, producers, processors, retailers, and governments have been increasingly relying on them to provide assurances to food safety. during this talk, professor zheng will first go over a conceptual framework for the market of private food safety standards through the lens of agri-food supply chain logistics, outlining how the key players in the market interact. second, he will summarize the development in this field. third, he will present his most recent research (with professor lijiao hu) on the effect of certifications on the safety of our food supply. they empirically explore the effects of private food safety certification on food safety performance in the meat, poultry, and egg products industry using the united states department of agricultural pathogen sampling results as the measurement for food safety performances. applying a penalized maximum likelihood method to establishment level data for 2015 through 2018, they found that the british retail consortium food safety standard (brc) certification decreased the probability of an establishment getting a positive test result for salmonella and campylobacter, while the safe quality food (sqf) certification decreased the probability of an establishment getting a positive test result for campylobacter and listeria. such results support the view that food safety certification could make our food system safer.
