Cooked garlic still kills bacteria
From Orlando, Fla., at the American Society for Microbiology meeting
Researchers have long known that chemicals isolated from raw garlic can kill a wide variety of bacteria, but the cooked herb hadn’t been tested. A new study suggests that cooked garlic can still kill bacteria, though less efficiently than does a raw bulb.
Microbiologist Chitra Wendakoon of New Mexico State University in Las Cruces worked with several common types of foodborne bacteria, such as strains of salmonella, listeria, and shigella. She created extracts of raw garlic and garlic and then boiled them for 15 minutes. Wendakoon added the boiled extracts to lab dishes in which the bacteria were growing.
