Foodborne diseases are among the most widespread public health problems. Yet only a small proportion of these illnesses come to the notice of health services, and even fewer are investigated. In developing countries even fewer cases are counted, primarily because of poverty and lack of resources for food safety management and food control services. In spite of underreporting, increases in foodborne diseases in many parts of the world and the emergence of new or newly recognized foodborne problems have been identified (Tauxe, 2002). Microbiological quality control criteria for food globally still rely on standard counts of coliform bacteria that were developed as indicators for fecal contamination. There is now ample documentation that these criteria are insufficient to protect against viral food-borne infections. For example high loads of infectious human pathogenic viruses have been detected in foods at retail that passed all microbiological control criteria, and this has led to discussions about the validity of proof for a recall. It is, therefore, important to understand the fundamental properties of food-borne. Viruses have emerged as causes of foodborne disease, according to data compiled by the Centers for Disease Control and Prevention. Viruses cause a wide range of diseases in plants, animals and humans. These infections do not occur at random: each group of viruses has its own typical host range and cell preference. Viruses were probably always a cause of food borne disease; however with recent developments in detection we are now able to confirm the presence of viruses. Previously, those outbreaks may have been recorded as having an unknown causative agent.

Viruses that cause gastroenteritis, among these are astrovirus, rotavirus, adenovirus, norovirus (formally Norwalk-like viruses), and SLV (Sapporo-like viruses). 2. Viruses that are transmitted through the fecal-oral route, including hepatitis A and hepatitis E. 3. Viruses that cause other illnesses, including enteroviruses Although food borne outbreaks are sometimes seen with rotavirus and astrovirus, these viruses typically affect children as opposed to adults. The viruses at the highest risk for food borne transmission are norovirus and hepatitis A virus. The reasons may be due to their extreme stability in the environment and their highly infectious nature (Koopmans et al., 2002).
The Norovirus belongs to the family called Caliciviridae. The norovirus causes gastroenteritis which is a condition that causes irritation and inflammation of the stomach and intestines. The norovirus is actually the most common cause of acute gastroenteritis.1

16) It is possible for foodborne illness to erupt in developed country due to improper handling and importation of food. There has been recent E.coli outbreak in developed countries like U.S (2006) and Germany (2011). However, the public health community is well prepared to respond to such
Tragedy struck in 2015, E- Coli cases started surfacing in the Pacific Northwest in late October, included August salmonella cases in Minnesota that sickened 64. Outbreaks of norovirus was traced to Chipotles in California in August and Boston in December that together sickened hundreds. On November 20, CDC (Centers for Disease Control) reported the outbreak had spread to Minnesota, California, New York and Ohio. Two weeks later, the CDC reported cases in Illinois, Maryland and Pennsylvania. (Jargon, Julie, & Newman, Jesse, 2016)
Norovirus is extremely contagious and is transmitted primarily via the fecal-oral route and is transmitted by way of fomites, consuming contaminated food or water, or contact with an infected person (2). It can also be transmitted if the vomit of an infected person becomes aerosolized (2). One study estimated that the average number of norovirus particles necessary to cause infection is as low as 0.5, meaning that of people who contracted a single norovirus virion, half will become infected (3). As of 2008, that is the lowest of any virus that has been studied (3). Norovirus is one of the few viruses that is transmitted mostly through contaminated food. This usually happens when an infected person fails to properly wash his or her hands after using the bathroom and before preparing food. Many people infected with norovirus are asymptomatic which increases the spread of the virus. Infected but asymptomatic food handlers have been the cause of several norovirus outbreaks (4). The virus can also build up inside filter feeding shellfish such as oysters, mussels, and clams if surrounding water becomes contaminated with human waste (5). A study performed in South Korea that collected shellfish and tested them for norovirus showed that it was present in approximately 27.9
E. coli may cause one of three different infections: urinary tract infection, neonatal meningitis, and or intestinal diseases. However, it most commonly causes intestinal disease. There are five classes of the bacteria that will cause this: enterotoxigenic E. coli, enteroinvasive E. coli, enterohemorrhagic E. coli, enteropathogenic E. coli and enteroaggregative E. coli. All five of these strains cause diarrhea. For
Rotavirus is a common cause of viral gastroenteritis for Australian babies and preschool children. Infection is caused by person-to-person contact such as touching contaminated hands or faeces (poo). It is possible to be infected with rotavirus several times. Rotavirus impacts the human systems in many different ways. It also has biological impacts on society through past, present and future predictions. In conclusion, Rotavirus affects a majority of the world and has a great effect on young children.
This transition of food consumption approach in order to avoid the obesity problem and health issues that are related to food. She talked about "Microbial Food Safety" that may lead to diseases after food consumption. In the U.S, there are numerous outbreaks have on foodborne illness over the last ten years and they are related to sprouts. Internationally, microbes could be transmitted among countries through seeds that are propagated far away from original location which is involved around people health safety. Domestically, Disease control publish an estimate for foodborne illnesses in the US every ten years. They have two publications focused on unspecified agents and major pathogens. The relationship between food and illness comes from foods that are suspected to cause of illnesses, but causes of these illnesses still unknown. Moreover, there are known 31 major pathogens comes from foods cause illnesses such as Norovirus and Clostridium perfringens etc, and ten of then are the major pathogens that
This essay will be about the disease gastroenteritis. Gastroenteritis is the inflammation of a human’s stomach and intestines. Rotavirus is the most common viral infectious agent responsible for causing gastroenteritis in children. In 1972, norovirus was identified as the first virus causing gastroenteritis. After this discovery, other viruses causing gastroenteritis were discovered, such as rotavirus, adenoviruses, calicivirus, and astrovirus. Before vaccines were introduced in 2006, Rotavirus was the leading cause of severe diarrhea in infants and young children.
Food safety is a high profile issue facing consumers, agricultural marketers, farmers and governments. In the United States, estimates of the number of illnesses each year from microorganisms in food range from 6.5 to 33 million people, while deaths could be as high as 9,000. Lost productivity from food borne illnesses are estimated to be in the range US$7 billion to US$23 billion per year. Just one incident in Japan in 1996 involving radish resulted in ten deaths and 9,000 people made ill.
Foodborne diseases are significant and important public health problems in United States causing numerous illnesses, hospitalizations and deaths of people. Centre for Disease control and Prevention report Nontyphoidal Salmonella, norovirus, Campylobacter spp., Toxoplasma gondii, Listeria monocytogenes, Clostridium perfringens, Escherichia coli O157 and Staphylococcus aureus as the major food borne pathogens significant in US. CDC estimates that roughly 1 in 6 peoples got sick with 128, 000 hospitalizations and 3,000 deaths each year in United States. Along with this, these diseases can cause substantial amount of burden through long term complications and sequelae. Understanding the overall human health impact of these
In my opinion, one of the scariest pathogenic viruses is the human rotavirus disease. Rotavirus is a disease that causes an infection in the intestines, and it is most common in infants and young children – however, anyone can be infected with rotavirus. Symptoms of rotavirus can include severe watery diarrhea, vomiting, fever, and abdominal pain. The diarrhea and vomiting can last anywhere from 3 to 8 days, which could potentially, and more dangerously, lead to dehydration.
Food insecurity and poor nutrition is an alarmingly large problem for low income families, especially in developing countries. Many strategies exist to fight this problem, although not many of these address all the factors contributing to it along with all the possible solutions to solve it. In many cases, multiple strategies must correlate and work together so that all the determinants of this issue are addressed and can fight food insecurity from different angles. This essay will discuss the significance of the problem, a range of possible strategies to solve the problem, and go into detail on a select few that will correlate and work together to solve different factors of food insecurity and poor nutrition.
There are more then 250 known foodborne diseases. Majority of the foodborne disease are infectious and are caused by bacteria, viruses, and parasites. Other foodborne diseases are essentially poisonings caused by toxins, chemicals that contaminate the food. All foodborne microbes and toxins enter the body through the gastrointestinal tract and causes symptoms such as nausea, vomiting, abdominal cramps and diarrhea. There is another symptoms that some people call as“stomach flu” may actually be a foodborne illness caused by a pathogen such as virus, bacteria, or parasite in contaminated food or drink. Some of the well-recognised food-borne pathogens, such as Salmonella spp. and Escherichia coli, seem able to evolve to exploit novel opportunities, for example fresh produce, and even generate new public health challenges, for example antimicrobial resistance (Newell
