Before You Cook: A Guide to the 5 Foods You Shouldn’t Eat from Your Vacation Rental

The convenience of a kitchen is a primary appeal of vacation rentals, but food safety experts warn that these spaces can harbor hidden risks. Contamination from previous guests and improper storage create potential health hazards. Understanding the specific foods you shouldn’t eat from your vacation rental is a critical step for travelers to prevent foodborne illness and ensure a safe stay.

The Unseen Risks of a Shared Kitchen

While vacation rentals offer a home-like experience, their kitchens lack the standardized cleaning and food handling protocols of commercial establishments. Unlike a personal home, the history of a rental kitchen is unknown. Previous guests may have handled food improperly, leading to cross-contamination, or left behind items that have expired or been stored at unsafe temperatures.

“A vacation rental kitchen is an uncontrolled environment,” said Dr. Angela Richards, a food microbiologist and senior fellow at the Institute for Food Safety. “You don’t know who was there before you, their state of health, or how they handled or stored the food items they left behind. The guiding principle must be: when in doubt, throw it out.”

The Centers for Disease Control and Prevention (CDC) reports that one in six Americans get sick from foodborne diseases each year. Many of these illnesses can be traced back to common pathogens like Salmonella, E.coli, and Listeria, which thrive in improperly handled or stored food.

A Traveler’s Guide: 5 Foods You Shouldn’t Eat From Your Vacation Rental

To mitigate risks, food safety professionals advise travelers to exercise extreme caution with items that are already present upon arrival. Here are five categories of food you should avoid consuming.

1. Opened Condiments, Jars, and Spices

That half-used bottle of ketchup or jar of mayonnaise might seem like a welcome convenience, but opened containers are a prime source for contamination. A previous guest could have double-dipped a utensil, introducing bacteria that can multiply over time, even in the refrigerator.

“Opened condiments are a gamble,” Dr. Richards explained in an interview. “Items like mayonnaise and creamy dressings are particularly risky if not kept consistently cold. Even dry spices can be contaminated with moisture or pests if not sealed properly.” The U.S. Department of Agriculture (USDA) recommends discarding any perishable foods that have been left at room temperature for more than two hours.

2. Perishables Left in the Refrigerator or Freezer

• While finding a carton of eggs or a package of bacon might feel like a bonus, these items should be avoided. You cannot verify the expiration dates or how long they have been stored. A refrigerator that was temporarily without power between guests could have allowed these foods to enter the “danger zone”—the temperature range where bacteria grow rapidly.
• The USDA defines this danger zone as being between 40°F (4°C) and 140°F (60°C). Perishable foods like meat, poultry, eggs, and dairy must be kept below 40°F to remain safe. Without knowing the rental’s recent power history, consuming these items is a significant risk.

3. Anything from the Ice Maker or Ice Trays

• Ice machines and trays are rarely, if ever, cleaned between guests. Mold and bacteria can easily colonize the dark, moist interior of an ice maker. Furthermore, if the rental uses unfiltered tap water, the resulting ice could contain contaminants.
• A 2017 study published in the Annals of Microbiology found that ice cubes from various sources, including domestic refrigerators, frequently contained diverse microbial populations. Experts recommend either washing and sanitizing ice trays before filling them with bottled water or simply purchasing a bag of ice from a local store for the duration of your stay.

4. Open Bags of Flour, Sugar, or Grains

Pantries in vacation rentals often contain partially used bags of dry goods like flour, pasta, or cereal. While less risky than perishables, these items can still pose a problem. Improperly sealed packages can attract pests, including insects and rodents, whose droppings can transmit disease. Moisture can also lead to mold growth that isn’t immediately visible. It is safer to purchase small quantities of these staples for your own use.

5. Foods Prepared with Shared Cutting Boards and Sponges

• The most significant risk in a vacation rental kitchen is cross-contamination. A worn, porous wooden or plastic cutting board can harbor bacteria deep within knife grooves, even after a superficial wash. If a previous guest cut raw chicken on the board, Salmonella bacteria could easily transfer to the fresh vegetables you are preparing for a salad.
• Similarly, used kitchen sponges are notorious for being one of the most germ-laden items in any kitchen. A study from Germany’s Furtwangen University found that kitchen sponges can harbor more active bacteria than a toilet. Always use a new, sealed sponge that you bring or purchase, and thoroughly wash and sanitize all cutting boards and utensils with hot, soapy water before use.

Ultimately, proactive prevention is the best strategy for ensuring food safety tips are followed during your travels. Bringing a small kit with a new sponge, a small bottle of dish soap, and sanitizing wipes can empower travelers to create a safer cooking environment. While the goal of a vacation is to relax, a few minutes of precaution can prevent an unpleasant illness from disrupting your plans.
