FDA Puts Listeria Prevention and Home Food Storage on the Agenda

The U.S. Food and Drug Administration is bringing Listeria monocytogenes prevention into the spotlight with a two-day public meeting on August 18 and 19, 2026. The event will be available in person and virtually, and will bring together government agencies, researchers, consumer groups, physicians, food manufacturers and retailers.

According to the FDA announcement, the meeting is the first in a planned series of public engagements on Listeria prevention. The agency says the discussions will consider new scientific developments, practical control measures and the experiences of different stakeholders.

The timing matters because listeriosis remains a serious food-safety concern despite years of prevention work. The FDA's meeting information describes Listeria monocytogenes as the fourth-leading cause of death from foodborne illness in the United States, with approximately 1,250 cases and 170 deaths annually. It also says reported incidence has remained essentially static for more than a decade.

Why the refrigerator is part of the story

Listeria is unusual among foodborne pathogens because it can survive and grow at refrigeration temperatures. That means chilling food is still essential, but cold storage does not automatically make contaminated food safe. The longer a ready-to-eat refrigerated food remains contaminated in the refrigerator, the more opportunity the organism has to multiply.

This is one reason the FDA meeting specifically includes consumer storage and use among its key areas. The agency is also looking at Listeria control during manufacturing, retail handling and the protection of vulnerable populations. The goal is not to create a new household rule overnight, but to identify better ways to reduce risk across the entire food chain.

At home, the most useful response is disciplined cold storage and careful cleaning. The FDA recommends keeping the refrigerator at 40°F (4°C) or below and the freezer at 0°F (-18°C). A refrigerator thermometer can help verify the setting instead of relying only on the dial.

A practical Listeria check for home cooks

Start with the refrigerator itself. Wipe up spills as soon as they happen, especially around ready-to-eat foods, dairy products and packages that may leak. Clean the inside walls and shelves regularly, then return food to the refrigerator promptly so it does not sit at room temperature.

Wash cutting boards, countertops and utensils that may have contacted food. The FDA advises cleaning these surfaces and then sanitizing them with a solution made from one tablespoon of chlorine bleach in one gallon of clean water. Follow the bleach label, ventilate the area and never mix bleach with other cleaning products. Wash your hands with soap and warm water for at least 20 seconds before and after handling food and after cleaning or sanitizing.

Remember that freezing does not eliminate or reduce Listeria. If a refrigerated ready-to-eat food is recalled or suspected of contamination, placing it in the freezer is not a safety fix. Follow the recall instructions, discard affected food as directed and clean any surfaces or containers that may have touched it.

Extra care for higher-risk diners

Listeriosis can be especially serious for pregnant women and their unborn or newborn babies, adults over 65 and people with weakened immune systems. The FDA identifies several food categories that require particular caution for these groups, including unpasteurized milk and milk products, queso fresco-type cheeses, raw or smoked fish, raw sprouts and certain other raw foods.

That advice does not mean every household must remove the same foods from its kitchen. It does mean that cooks should check labels, follow pasteurization information and consider who will be eating before serving higher-risk foods. When preparing food for someone in a vulnerable group, choose clearly pasteurized products and take extra care with refrigerator hygiene, cross-contamination and storage time.

The FDA's meeting will also discuss ready-to-eat foods such as deli meats, prepared foods and some raw or processed fruits and vegetables. These foods may be eaten without another cooking step, so preventing contamination during handling and storage is especially important.

What to watch from the meeting

The August agenda covers advances in understanding and controlling Listeria, best practices for prevention, dose-response modelling, food-safety management systems in retail environments and the effect of changing demographics and dietary patterns. The FDA also plans listening sessions and an opportunity for interested parties to submit comments.

For home cooks, the most relevant takeaway is straightforward: refrigeration is a control measure, not a guarantee. Keep cold food genuinely cold, clean spills quickly, wash hands and food-contact surfaces carefully, and use extra caution when cooking for people more likely to develop severe listeriosis. Those habits remain useful while regulators and scientists work on the larger gaps the FDA meeting is designed to address.
