Lyophilized Preparations Of Bacteriocinogenic Lactobacillus Curvatus And Lactococcus Lactis Subsp Lactis As Potential Protective Adjuncts To Control Listeria Monocytogenes In Dry-Fermented Sausages

Methyl oleate was used as a primary carbon source and as an alternative inducer for the production of an extracellular lipase, Lip2, in Y. lipol.vtica strain LgX64.81 grown in a 20-1 bioreactor. The lipase-encoding gene, LIP2, was investigated during culture on methyl oleate using a pLIP2-LacZ reporter fusion and we provide evidence for the involvement of methyl oleate in its regulation

Traceability, Liability, and Incentives for Food Safety and Quality

Recent food scares such as the discoveries of Bovine Spongiform Encephalopathy and E. coli-contaminated spinach have heightened interest in food traceability. Here, we show how exogenous increases in food traceability create incentives for farms and marketing firms to supply safer food by increasing liability costs. We model a stylized marketing chain composed of farms, marketers, and consumers. Unsafe food for consumers can be caused by either marketers or farms. We show that food safety declines with the number of farms and marketers and imperfect traceability from consumers to marketers dampens liability incentives to supply safer food by farms.
