Rust and Food Pathogens
Country: United States
Date: October 2006
I know the USDA does not allow rusty equipment used
in processing plant but I want know what effect does rust have on
pathogen growth? I'm thinking rust is considered as> > free-radical--bad
for your health--and bacteria loves iron but how> > much is too much? A
piece of meet place on rusty equipment gets cooked on high heat--how does
heat affect it?
I am pretty sure that rust is not a free radical; it is Iron Oxide which is
not chemically reactive. Iron bacteria are not usually pathogenic so I don't
think rust in food preparation equipment is of much concern.
