Some pre- cooked ham in a package recently went 'off' in our fridge. A

"A few weeks" is plenty of time for food to go bad even if it's refrigerated.

The fridge works fine. The temperature in its freezer compartment
maintains at 0 deg. F. as always.

Weather (for here) has been a little warmer of late. Last few days
around 70 Deg F. Not hot at all by most people's experience! The air
balance between freezer and fridge compartments does not appear to
have changed.

The temperature in the meat tray which also contains some bacon and
sausages (they're OK) is just a tad below 40 deg F. Which seems
normal. Milk and other items in the main fridge compartment have not
spoiled.

40F *is* normal -- as shown by your milk.

Can someone suggest a suitable 'food' news group to address my
question. Maybe ham is just a little more liable to to spoil? Or it
was just bad batch? Another slightly newer package is OK.

No, you just left it too long after opening it. That's all. Expecting an
opened package of meat to keep for several weeks is unreasonable.
