What is up with tomato sauce being nut contaminated?

[brownie]

I am wondering why all these tomato products are an issue.  It is not something I would anticipate being an issue.  For instance, warning on Ragu, Pizza Hut pizza sauce, Whole Foods pasta sauce, and when I called Baby Ray's BBQ they told me not to use it.  What happens in a tomato facility that puts products at risk?  Just seems odd and hard to explain to others.

Pesto?

Pesto?

That's what I thought.  It could be pinenuts or walnuts in pesto.

I'd say pesto as well...

Could be consolidation and larger processing centers, too.

PLAIN tomato products by brands like Del Monte and Contadina tend to be uncontaminated.

But...

sauces which are made in multipurpose, leviathan, contract manufacturing facilities may well ALSO make/process/package satay sauce or god-knows-what on the same lines.  Or maybe they just want to reserve the possibility.  Most individual package condiments are in this category, fwiw.  The few manufacturers either do:  a) only ketchup, or b) anything that comes in a foil, plastic-lined, single-serving pouch.  On the same lines, I mean.

<sigh>

This really isn't necessarly CYA labelling.  But it also is likely to be okay for those who don't have super-low thresholds.  IMMV, of course.

hmmm..never thought about that.  So honey for chicken nuggets is probably a potential for cross contamination.  Other than ketchup, that is probably the only "single-serve" we typically use, but good to know.  I bet Heinz makes their own ketchup...can't imagine them allowing anyone else to to it but who knows.
