MMWR on Multistate Outbreak of E. coli O26 Infections Linked to Raw Flour

Most consumers do not recognize that raw, or uncooked, flour, is considered a health risk as this item is a raw agricultural product that has not undergone a kill step to eliminate pathogens.

If You Travel, the CDC Has Info About Food and Water Safety Abroad

If you travel, or if you are going to start traveling once the pandemic eases, the CDC has information about food and water safety abroad that is important.

Hot food is usually safe. The only thing that reliably destroys most bacteria and pathogens is heat. The exception is toxins produced by some bacteria as they grow, and spores of some bacteria, such as Clostridium botulinum.

Most bacteria and other pathogens require … [Read more...]

CDC Health Advisory For Extensively Drug-Resistant Salmonella Typhi
