General tips for ordering takeout and eating out, on vacation, or on the go:
Always ask for your food to be cooked thoroughly. Especially if it contains meat, fish, or eggs.
Follow the "Two-Hour Rule". If you're taking home leftovers, be sure to get them into a fridge within about two hours of being served to be safe from bacteria growth — this goes for both takeout and restaurant doggie bags.
Never leave your leftovers (or groceries) in a hot car for an extended period of time. Bacteria can grow rapidly in warmer conditions (between about 40-140 degrees Fahrenheit).
Steer clear of too many unhealthy foods. Fried food, anything with a lot of sugar, fat, or sodium, or foods that may make you uncomfortable, give you heartburn, or cause you to gain too much pregnancy weight should be avoided — especially in excess — when possible. (Consult your doctor to discuss healthy pregnancy weight gain, or if you're having issues with indigestion in any way.)
