There were two non-RTE samples of frozen spinach with E. coli ranges of 1,100 cfu/g and 570 cfu/g.
Sure directions to buyers to entirely cook frozen greens intended by the producer to be non-RTE used to be lacking on the packaging of 37 of 399 samples tested.

Total, 85 respondents acknowledged they both customarily or never be conscious cooking directions on the packaging of greens, fruits and herbs when making ready frozen food for prone teams.
Combining outcomes from both surveys displays there were a little percentage of non-RTE frozen greens which some buyers acknowledged they incessantly spend uncooked and that had been corrupt with low ranges of Listeria monocytogenes.
