High Cost of Foodborne Illness

 

A single outbreak of foodborne illness can cost a foodservice operation as much as $75,000 in legal fees, medical claims, lost employee wages, cleaning and sanitizing, discarded food supplies, and lost income from negative publicity and/or being shut down. That figure increases dramatically if the incident involves death or serious injury.

Amoeba entrapping Legionella pneumophila bacterium

 

 

This electron micrograph depicts an amoeba, Hartmannella vermiformis (orange) as it entraps a Legionella pneumophila bacterium (green) with an extended pseudopod.

After it is ingested, the Legionella pneumophila bacterium can survive as a symbiont within what then becomes its protozoan host. The amoeba then becomes what is referred to as a "Trojan horse", for by harboring the pathogenic bacteria, the amoeba can afford them protection, and in fact, in times of adverse environmental conditions, are able to metamorphose into a cystic stage enabling it, and its symbiotic resident pathogens to withstand such environmental stresses.
