A: No.  Allergen disclaimers are often printed as a stringency and even when the potential trace cross-contamination is well below the threshold of halachic significance.

Q: Do whole frozen green beans need a good hechsher or as long as it has any hechsher?

A: In general, frozen fruit or frozen vegetables don’t need any hechsher unless they are from Israel or unless they are prone to infestation – with the exception of frozen strawberries which even some of the stricter insect policies accept, and a minority opinion allows any pre-washed frozen spinach, broccoli, cauliflower, or kale.  (See here for halachic background.)

Q: Is all scotch kosher?

A: There are four levels of scotch vis-a-vis kosher status.  Some scotch is certified and therefore accepted by all; most is not.  Some do not advertise a special finish (Sherry, Port, Madeira, Oloroso, Sauterne, Shiraz, Dual cask finish, or Double-Matured) and are nearly universally accepted as kosher even though they are not supervised.  Other scotches do list one of the aforementioned special finishes, and this category is subject to unresolved debate – many do not consider them kosher due to the release of non-kosher wine flavor from the barrel walls into the scotch, whereas many others do consider them kosher either because in actuality an insignificant amount of flavor is released or because the amount that is released is halachically nullified.  The final category consists of scotchs that are produced by Jewish-owned companies that do not sell their chametz for Passover.  To the best of my knowledge this category is considered by all to be non-kosher.

Q: Are Snyder’s pretzels with an OU-D actually dairy?

A: According to the OU, Snyder’s pretzels are actually DE (diary equipment) except for the butter flavored variety, and can therefore be eaten even immediately after one has consumed meat.
