As the New York City Health Department invited public comment on proposed rules and outlined procedures to guide the implementation of New York City’s new restaurant grading system, Don Sapatkin of the Philadelphia Inquirer reported this morning that most food establishments don't publicize even their most positive inspection reports, and no government in the Philadelphia region requires

Shigella flexneri inhibits apoptosis in infected epithelial cells. In order to understand the pro-survival effects induced by the bacteria, we utilized apoptosis-specific microarrays to analyze the changes in eukaryotic gene expression in both infected and uninfected cells in the presence and absence of staurosporine, a chemical inducer of the intrinsic pathway of apoptosis.

I have fond memories of licking the beaters while mom was making cake and frosting. But, then I learned about salmonella in raw eggs, and became more cautious around my own kids – but not completely. Admittedly, the risk is low; the risk is much greater when eggs are pooled to make large batches of cakes or sauces.

An emerging trend in several mainstream media stories over the past year is that some of the biggest food suppliers – Costco, Wal-Mart, McDonald’s, Burger King – have the best food safety requirements. Quality is a different issue and largely based on personal preference and lifestyle choices. Cool.

Larry Corry, a veterinarian, is president of the American Veterinary Medical Association, writes in this letter that in “Cows on Drugs” (Op-Ed, April 18), Donald Kennedy states that giving antibiotics to large numbers of animals raised for food leads to antibiotic resistance in humans.

Salmonellosis is a frequent disease in poultry stocks, caused by several serotypes of the bacterial species Salmonella enterica and sometimes transmitted to humans through the consumption of contaminated meat or eggs. Symptom-free carriers of the bacteria contribute greatly to the propagation of the disease in poultry stocks.

Cells take advantage of a biologically ancient compartment to sequester prions, an action that can initially prevent the prions’ phenotypic expression, according to Whitehead Institute researchers. While in this compartment, less heritable prion plaques mature to a more transmissible state.
