I don’t support dumpster diving, unless it’s a necessity. There is a lot of stuff that can make you really sick that goes into those. But, if you are forced because of your situation, be mindful of signs of food spoilage and types of food that are most risky.

Spoilage signs:

• visible mold (green/white/blue/fuzzy, musty odor)
• visible bacterial growth (most likely on moist and liquid items - yellow tint in items that should be clear, white streaks across item surface that shouldn’t be there, smelling “off” - not how it should smell)

High-risk items:

• Meats
• Fish
• Eggs
• Dairy
• High-moisture foods
• Sauces
• High-sugar foods (at high-enough concentrations, sugar is preservative but, we’re talking candied ginger there, not koolaide)

Safest foods are going to be things like dried beans and other legumes (when cooked properly).

Another suggestion would be to keep an eye on late night line cooks. Be friendly and avoid being a nuisance to them or their customers. Some might be friendly, understand your situation (possibly from experience), and offer fresher food than you get from a dumpster. If you build rapport, some might be willing to barter for help with closing tasks.

Yet another suggestion: look into non-profit orgs in your area. If you are not able to afford food for lack of work, some may be able to help.
