food irradiation -Reply



There is some experience with contamination of irradiated
products (not food), but to my knowledge only in one (1)
irradiator which used Cs-137 capsules manufactured at the
Waste Encapsulation and Storage Facility (WESF) at
Hanford. One (1) of two-hundred fifty-two (252) capsules at an
irradiator here in Decatur, GA leaked in 1988 ...
contaminating the shielding and cooling water, product and
the building ... and a $45 million, 3.5 year cleanup ensued.

Assuming that the sources used to irradiate food products
are "relatively insoluble" (i.e. Co-60) and regularly leak tested,
there should not be a concern about contamination of the
product. The same claim cannot be made with "soluble"
sources, such as CsCl. I cannot speak to radiolytic chemical
production in the food itself ... I'll have to leave that one to
somebody else.

I think that the message is clear that Hormel would like lots
of positive calls to their toll-free number. For those of us who
are not food safety experts, how about a technical discussion
(with references) concerning the pro's and con's of food
irradiation?
