Where there is more livestock than people in the United States

The United States Department of Agriculture provides annual inventory data on livestock, crops, and various products. The tool is very ad hoc government-looking, but it seems to work well enough.

Erin Davis made some fun maps that use the data at the county level to compare livestock populations to people populations. Davis compared animals individually, but the multivariate one that compares cows, chickens, and pigs is my favorite.

One Team, One Purpose: The Role of USDA’s Food Safety and Inspection Service in Keeping Food Safe

One Team, One Purpose: The Role of USDA’s Food Safety and Inspection Service in Keeping Food Safe | www.aphlblog.org

Guest post by Julie Schwartz and Kristen Booze (Felicione), Office of Public Affairs and Consumer Education, FSIS, USDA

There is nothing like a spicy beef chili to keep your belly warm in the fall and winter. Wherever you pick up your recipe ingredients this season, it is the mission of United States Department of Agriculture’s Food Safety and Inspection Service (FSIS) to ensure meat, poultry and processed egg products sold in your supermarket are safe, wholesome and accurately labeled. This means you can rest assured the food you purchased is safe to serve your family.

FSIS prides itself on keeping America’s food supply among the safest in the world along with many food safety partners, like APHL. And yet, the Centers for Disease Control and Prevention (CDC) estimates foodborne bacteria sicken about 48 million Americans (1 in 6) every year. In addition, foodborne illness hospitalizes approximately 128,000 people and causes about 3,000 deaths annually. Foodborne illness is certainly a public health concern.

Foodborne illness is preventable. And it disproportionately affects America’s most vulnerable populations, such as children, the elderly and those with compromised immune systems. This knowledge drives more than 8,600 hardworking FSIS employees to report to work every day across the United States. Their mission is to make certain the food Americans feed to their families will not cause foodborne illness. They operate at many levels as one team with one purpose: to protect public health by keeping the U.S. food system safe from farm to table.

The First Line of Defense

Inspection personnel form the core of FSIS. These 8,000 individuals are responsible for performing inspection activities at more than 6,400 food-producing and import establishments. FSIS is also the largest employer of veterinarians in the United States. Many of the FSIS Public Health Veterinarians (PHVs) help oversee the effectiveness of the food safety systems, readily applying their expertise in epidemiology, pathology, risk management and humane slaughter.

FSIS inspection personnel provide the first line of defense against diseased and adulterated meat and poultry; these products must be inspected and then labeled with the USDA Mark of Inspection before they are sent to grocery stores or restaurants. FSIS employees approve the descriptive labels on meat, poultry and egg products, such as ‘fresh’ and ‘halal,’ to ensure they are truthful, not misleading and contain the information necessary to keep you, the consumer, informed and protected.

Investigators are the eyes and ears of FSIS. These employees enforce policies and statues, and impose sanctions according to agency laws and policies to keep food safe for the consumer. Investigators also work to reduce wasteful practices, fraud and mismanagement; and ensure that criminal, administrative and civil sanctions are carried out.

A Modern, Science-Based Approach

To prepare for existing and emerging food safety threats, FSIS has stressed a science-based approach towards policy developments to achieve the statutory mission laid out by Congress. An example of how the agency adapts its policy to prevent foodborne illness is the Modernization of Poultry Slaughter Inspection regulation, which made the first major updates to U.S. poultry inspections in more than 50 years. The new requirements mandate that all poultry companies take scientifically based measures to prevent contamination, rather than addressing it after it occurs. For the first time, poultry facilities will be required to perform their own microbiological testing to demonstrate they are controlling for pathogens that cause illness, like Salmonella and Campylobacter. When fully implemented, poultry companies will have to meet new control requirements for these bacteria, and an estimated 5,000 additional foodborne illnesses will be prevented each year.

A broad team of scientists at FSIS work to investigate foodborne outbreaks and prevent foodborne illness, similar to scientists within public health laboratories. They provide the public health and scientific basis for the development of food safety policies, emergency response, outreach efforts, data collection initiatives and research priorities. They also provide the scientific basis to support preparedness, response and recovery initiatives for all threats affecting the food supply.

Ensuring meat, poultry and processed egg products are safe and wholesome requires many motivated and highly trained professionals working simultaneously as one team with one purpose. The work performed by FSIS employees touches every community in the nation and its territories. From the inspection of domestic product, imports and exports; conducting risk assessments; and educating the public about the importance of food safety, USDA is there working to build a better modern public health system that meets the evolving needs of the farm-to-table continuum.

 

 

 

5 Things You Didn’t Know (but Need to Know) about Listeria

By Michelle Forman, senior specialist, media, APHL

Listeria has reared its ugly head (and tail – flagella, technically speaking) seemingly quite a bit recently. According to FDA, there have been 14 recalls due to possible Listeria contamination so far this year. (Five of those were linked to the same spinach supplier.) And USDA’s list shows another three. While most of these recalls have not been linked to illnesses*, Listeria is extremely serious and considered a high-priority within the US food safety system. What is this nasty bacteria and why is it so serious? Here are five things that you didn’t know (but need to know) about Listeria.

5 Things You Didn’t Know (but Need to Know) about Listeria | www.APHLblog.org1. 90% of people who get listeriosis (the infection caused by Listeria monocytogenes) are part of a high-risk group such as pregnant women, adults over 65 years and people with weakened immune systems. In fact, pregnant women are about 10-20 times (depending on the source) more likely and the elderly are four times more likely to get listeriosis than the general population. If you’re part of one of these groups, take Listeria risk very seriously.

2. Listeria has a very high mortality rate. CDC estimates that there are about 1,600 cases each year and 260 die (approximately 16%). By comparison, CDC estimates 19,000 Salmonella cases each year and 380 die (approximately 2%).

Listeria is unlike many other foodborne pathogens because it can grow even in the cold temperature of the refrigerator making it extra important to avoid cross contamination from uncooked meat, fish or other high risk foods. Like other foodborne pathogens, proper cooking is the most effective way to kill Listeria that is lurking on your food.

4. The incubation period for Listeria is 3-70 days. That means it could be up to 70 days after Listeria entered your body before you get sick. Many people who get foodborne illness often point to the last thing they ate as the culprit, but that’s often not the case especially with Listeria. For the purposes of an outbreak investigation, epidemiologists will look back even further – as much as 120 days prior to when a person became ill – to be sure they are really looking at every possible suspect. Can you remember what you ate 70 days ago? Or even 120 days ago?

5. The US food safety system takes Listeria extremely seriously. There is an enhanced surveillance system led by CDC called the Listeria Initiative which requires health care providers to report listeriosis cases; requires public health officials to promptly interview anyone with listeriosis to gather information that could help identify the source of infection; and requires clinical labs to send positive samples to public health laboratories for subtyping using PFGE (DNA fingerprinting). The DNA fingerprints are uploaded to PulseNet, the national network of public health and food regulatory agency laboratories that connect foodborne illness cases together to detect clusters of bacteria that make people sick. All of this helps accelerate outbreak detection and surveillance, and decreases the amount of time it takes to stop an outbreak from progressing.

* While there have been 17 recalls due to possible Listeria contamination, most have not been linked to illness. Five national PulseNet clusters of illness have been detected and reported to epidemiologists this year. Four of those clusters have led to epidemiologic investigations. As of now, three of those investigations are still open and active. One of those investigations has led to a confirmed source and is still considered active.

Minimal landscape maps

Grass minimal map

Designer Michael Pecirno experiments with single-subject maps in his project Minimal Maps. No boundaries, just landscape.

The data provided by the USDA is incredible and includes a tremendous wealth of information that makes up the composition of America. By pulling this data and extrapolating specific categories I've been able to produce a number of unique and explicit maps that aim to push us away from the ubiquitous and low-resolution (regarding information content) physical and political map.

It still amazes that detailed geographic data like this exists.
