I was at Trader Joe's today, and saw the salmon patties they'd listed in their mailing this week. There were no eggs listed in the ingredients, but no information about cross-contamination at all, so I asked the store manager if he knew what the x-contamination warnings might be, and he looked them up. He said, in the same breath, "They should be safe, though they are produced on equipment shared with eggs". He then said, "I think this is a USDA-inspected facility", I pointed out that the box said they were produced in Thailand, and he said, "No, it's not, but because of the way they're processed, we don't think cross-contamination is an issue." That was about all I got in terms of an explanation. It was a bummer, because DD loves salmon, and these looked like a quick fix on a busy night, but we're not risking it.
I wish they'd just label shared lines, too.
