Food Safety After Power Outages

The following information is summarized from FDA and other sources. Further information on food safety during natural disasters can be found at: http://www.cfsan.fda.gov/~dms/fsdisas.html#s2.

General Food Safety of Refrigerated Foods

Refrigerated foods that can be held at temperatures above 40ºF until power returns include:  hard cheeses, butter, margarine, fresh fruits, fruit juice, fresh unpeeled vegetables, salad dressing, ketchup, mustard, olives, pickles, jams, jellies and peanut butter.

For all other products, most refrigerated foods are safe if the power outage was only 2-3 hours and if foods were held above 40ºF for 2 hours or less; however, for those who were without power for several days, most refrigerated foods should be discarded. If you are unsure how long products have been held above 40ºF, DISCARD the products. Foodborne pathogens can grow very quickly in some foods held above refrigeration temperatures; visual appearance and odor cannot be used to assess the safety of food products.

General Food Safety of Frozen Foods

If foods still contain ice crystals, they can be refrozen safely. Thawed fruits, fruit juices and fruit pies will be safe to eat; however, discard these products if they have come in contact with thawed meat drippings or if they have signs of spoilage, such as off-odors due to fermentation. All other thawed foods should be discarded. PNW 296 – Freezing Convenience Foods, page 3 has information about safety of frozen foods that have thawed.

Appliance Maintenance during a Power Outage

It is recommended to have appliance thermometers in refrigerators and freezers to help assess product safety.

During a power outage, keep freezer and refrigerator doors closed as much as possible. Try to keep the cold air in the freezer (a large, full freezer can hold freezing temperatures for about 2 days, a half-full freezer will keep food frozen for about 1 day) and the refrigerator (if unopened, will maintain a cold temperature for approximately 4 hours).

If the power outage is expected to last for an extended period, dry ice and ice blocks can be used to keep foods cold. Handle dry ice with caution. Separate dry ice from food products using a piece of cardboard; place the dry ice on top of the cardboard. Fifty pounds of dry ice will keep a full, 18-cubic foot freezer cold for two days (a general rule is to allow 2-3 pounds of dry ice per cubic foot of freezer space).

Safety of Specific Food Products

Meat, poultry and seafood products, including hot dogs and lunch meat. Frozen meats that have intact ice crystals and have an internal temperature less than 40ºF may be refrozen. Variety meats, such as heart and liver, should not be refrozen under any circumstances. Meat products at temperatures above 40ºF for more than 2 hours are potentially unsafe and must be discarded.

Hard cheese, butter and margarine. Well packaged products should remain safe; if odors or mold develops, discard the items.

Milk products and mayonnaise. Discard if held above 40ºF for more than 2 hours. This category includes milk, cream, yogurt, and soft cheeses. Ice cream should be discarded if it has partially thawed.

Fresh Eggs. Discard if held above 40ºF for more than 2 hours.

Fresh fruits and vegetables. Normally safe. Observe appearance for mold, sliminess or yeasty smell, discard if appearance is poor.

Frozen fruits and vegetables. If ice crystals are still intact and food has remained at 40ºF or less, these products may be refrozen; otherwise, discard the product.

Fruit juice. Refrigerated juices are safe without refrigeration; however, if mold, cloudiness, bubbling or off-odors (yeasty, fermented) occur, the product should be discarded. Frozen juices with intact ice crystals or if held at 40ºF for less than 2 hours may be refrozen.

Salad dressing, ketchup, mustard, olives, pickles, jams, jellies and peanut butter. May be kept unrefrigerated until power returns.

Mixed food items, including cooked pasta, stews, casseroles, soups, potatoes, custards and puddings. Discard if held above 40ºF for more than 2 hours. This category includes leftover foods.

A new study by researchers at Washington State University shows that mechanical harvesting of cider apples can provide labor and cost savings without affecting fruit, juice, or cider quality.
The study, published in the journal HortTechnology in October, is one of several studies focused on cider apple production in Washington State. It was conducted in response to growing demand for hard cider apples in the state and the nation…MORE

SubsurfaceIrrigationWSU wins national award for water-saving research

By Sylvia Kantor, College of Agricultural, Human & Natural Resource Sciences

Water scarcity – one of the toughest challenges predicted for the 21st century – is being addressed by Washington State University. As part of a multistate research program, WSU is among 19 land-grant universities honored recently for their efforts to help farmers irrigate their land more efficiently, especially during droughts and water shortages.
“A safe, reliable supply of water is inextricably linked to food security,” said Sonny Ramaswamy, director of the USDA National Institute of Food and Agriculture…MORE

Apples-USDA-ARS-350An apple a day could keep obesity away

By Sylvia Kantor, College of Agricultural, Human & Natural Resource Sciences

PULLMAN, Wash. – Scientists at Washington State University have concluded that nondigestible compounds in apples – specifically, Granny Smith apples – may help prevent disorders associated with obesity. The study, thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest, appears in October’s print edition of the journal Food Chemistry. “We know that, in general, apples are a good source of these nondigestible compounds but there are differences in varieties,” said food scientist Giuliana Noratto, the study’s lead researcher. “Results from this study will help consumers to discriminate between apple varieties that can aid in the fight against obesity.” MORE

By Rebecca E. Phillips, University Communications

PULLMAN, Wash. – Drug abuse, acts of rampage – what’s really the matter with kids today? While there are many places to lay blame – family, attitude, peers, school, community – a new study shows that those risks vary in intensity from kid to kid and can be identified.

Scientists at Washington State University and Pennsylvania State University have found a way to spot the adolescents most susceptible to specific risk factors for delinquency MORE

Extension collaborates with communities to create a culture of life-long learning and is recognized for its accessible, learner-centered, relevant, high-quality, unbiased educational programs.

MudflatImpact: Burrowing Shrimp and Invasive Eelgrass

Shellfish production in Washington is a $60 million a year industry. Several major pests plague this industry, resulting in major crop loss. One of the most important pests is subterranean burrowing shrimp. These shrimp bioturbate (stir up) the sediment, causing the oysters to sink and die. For the past 60 years the industry has been using the insecticide Sevin to control this pest, but due to lawsuits its use was phased out in 2012. Without alternative control for shrimp, tens of millions of dollars in annual crop revenue will be lost and the industry will quickly lose its economic viability in southwestern Washington.

PoultryFarmImpact: The National Livestock and Poultry Environmental Learning Center

The Environmental Protection Agency has identified agriculture as the leading contributor of pollutants to the nation’s rivers, streams, lakes, and reservoirs. These reports often do not separate animal agriculture from other agricultural enterprises, but they do note that pathogens, nutrients, and oxygen-depleting substances associated with manure are three of the top five pollutants. Some emerging issues related to manure management include: endocrine disruptors (hormones), pharmaceuticals (antimicrobials), and antibiotic resistance in bacteria. Adopting farm practices that minimize the environmental impact is important for food safety.

BiosolidsImpact: Biosolids and Compost

Biosolids are the solids produced during municipal wastewater treatment. Composts are made from a variety of organic materials, including both urban and agriculture sources such as yard trimmings, biosolids, storm debris, food waste or manure, and food processing residues. While these materials have traditionally been viewed as waste, they can play a valuable role as soil amendments in urban and agricultural settings. They provide nutrients and organic matter and they sequester carbon, thereby conserving resources, restoring soils, and combating climate change.
