What is the difference between salmonella and campylobacter

Campylobacteriosis is an infectious disease caused by the bacteria Campylobacter. Campylobacteriosis causes a severe form of diarrhea that lasts weeks in healthy individuals, while in persons with immune compromised systems Campylobacter may spread to the bloodstream and eventually result in death. Campylobacteriosis is the most reported food-related infection in humans worldwide. Salmonellosis is the second most reported food related infection in humans, caused by the bacteria Salmonella.

Salmonellosis may cause severe diarrhea in healthy individuals and death in immunocompromised persons. While incidences of Salmonellosis have been decreasing, Campylobacteriosis remains at the top of the list of foodborne pathogens that need to be tackled. These data come from additional experiments performed on the full scale IA Poultry equipment off-line outside a slaughterhouse process line.

The full scale testing equipment for pilot scale studies is designed as a loop, where the chain goes around itself, in and out of the treatment zone. This design allows for continuous treatment of broilers under off-line conditions. In this way the treatment time inside of the chamber can be varied from 6, to 14, carcasses per hour.

Listeria monocytogenes usually causes illness in vulnerable groups such as pregnant women, babies, the elderly and people with reduced immunity.

Among these groups, the illness is often severe and life threatening. Most strains of E. In the UK, the most common type is E. Although, most strains of these bacteria are harmless, several are known to produce toxins that can cause diarrhea. One particular E. Campylobacter is the most common identified cause of foodborne disease. It has been found mainly in poultry, red meat, unpasteurised milk and untreated water.

The questionnaire was written in German, and an English translation is available in the supplements. The panel provider GapFish recommended surveying at least consumers in Germany to obtain a good demographic representation and ensure a low margin of error. GapFish is a company and the operator of a panel platform where participants are registered and can be selected according to personal data such as age, gender and occupation.

Only persons with German language skills could participate, which might have partly excluded first-generation immigrants. To ensure representativeness regarding age and geographical location, the study population was proportionally stratified according to federal state, gender and age group. Sampling was continued until all strata were complete. If a stratum was complete, further participation was refused. Ultimately, responses from consumers were included in the analysis.

Data collection started on 11 August and was completed on 20 August The responses of consumers who had answered all questions completely were included in the statistical analysis. We did not have to remove any incomplete answers, as complete answers were submitted directly by the panel provider. Exceptions from completeness were made regarding questions on the level of education, primary residence, number of children in the household and household income after tax.

There was an option for participants to indicate that they could not answer the question or did not want to answer it. If a participant selected one of these answer options, this answer was not considered in the univariable and multivariable analyses, thus reducing the item-specific sample size. Descriptive statistics included frequency tables concerning questions about Salmonella , Campylobacter and Toxoplasma. Univariable associations between categorical variables were analysed by cross-tabulation and chi-square statistics.

The level of significance was set to 0. Whenever possible, odds ratios ORs were calculated to compare the odds of a certain event in one group to those in other group.

First, three different target variables were examined. In the first set of chi-square tests, the target variable was defined as the general level of knowledge of Campylobacter among consumers. The influence of various factors, such as age and gender, on the probability that the participant had heard of Campylobacter was investigated. In the second model, consumer knowledge of the transferability of Campylobacter via meat was used as the dependent variable. These questions could only be answered by consumers who had already heard of Campylobacter.

Here, the influence of various factors, such as age and gender, on the likelihood that the participant knew that Campylobacter could be transmitted to humans via meat was investigated. Third, it was investigated whether the different levels of consumer knowledge about possible protective measures against Campylobacter had an influence on the likelihood that consumers were aware of the transferability of Campylobacter via meat.

Consumers who had never heard of Campylobacter before were not asked this question and therefore could not be included in the analysis. The latter test was also performed for Salmonella and Toxoplasma. Categorical variables were analysed separately in the univariable chi-square tests and were then included in subsequent multivariable logistic regression models.

This procedure was only conducted for the first two target variable analyses. The final models were identified through a manual backward selection process. In each step, the variable with the highest p -value was removed.

After the removal of one variable, the change in the regression coefficients of the remaining variables as well as the change of model R-squared were investigated. Two-way interactions between explanatory variables were considered in the multivariable model and were removed, since all interactions turned out to be not statistically significant.

A total of A total of 2. Of all respondents, almost half An overview of general knowledge about Campylobacter , Salmonella and Toxoplasma from different consumer groups is shown in Table 1. Approximately Of the to year-old participants, Of those who had at least a secondary school certificate, Of all respondents, This included agricultural holdings, meat sales, slaughtering and processing, food monitoring and animal transport.

Of the participating veterinarians, Among consumers with high incomes, Of consumers who were not actors in the food chain, 2. On the other hand, Of the women, The percentage for men was Approximately one-quarter of respondents with children Of those without children, Consumers who had at least indicated knowing about Campylobacter, Salmonella or Toxoplasma were asked if the respective pathogen was transmissible via meat.

Of those consumers who did not know how to protect themselves against Campylobacter infection, In comparison, Of those consumers who did not know how to protect themselves against Salmonella infection, Approximately half Of those consumers who did not know how to protect themselves against Toxoplasma infection, The level of knowledge varied significantly between different consumer groups concerning Campylobacter.

All other variables tested, such as gender, location of main residence, state affiliation, frequency of cold cut and meat consumption, number of children in the household and household income after taxes, were not statistically significantly associated with the level of knowledge about Campylobacter at the univariable level Table 5.

Selected influencing factors were included in the multivariable logistic regression model. In addition to the variables that were statistically significant in the univariable analysis, no further relevant potential risk factors or confounders were identified for inclusion in the multivariable model. In the final logistic regression model, the results of the univariable tests could be confirmed. The to year-old participants were slightly more than 2.

We could also show that consumers with a higher level of education were significantly more frequently informed than those with a lower level of education. Participants who were not actors in the food chain were significantly less frequently informed about Campylobacter than those in the food chain. This also applies to non-veterinarians in comparison to veterinarians. All other variables examined did not show significant associations Table 6.

Those who knew how to protect themselves against Toxoplasma infection knew approximately 2. Campylobacteriosis was the most frequently reported zoonosis throughout the European Union in , and salmonellosis was the second-most common zoonosis to be reported in the European Union [ 2 ]. In addition to Europe, the number of cases of campylobacteriosis has also increased in North America and Australia [ 21 ].

The significant increase in the number of cases from below 55, in to more than 70, in in Germany highlights the importance of raising consumer awareness of Campylobacter. One reason for the increased case numbers could be that human consumption of poultry meat in Germany increased from Another reason for the increasing case numbers, especially in the summer months from June to September, could be the increased ambient temperature.

Yun and colleagues [ 23 ] showed that the increase in ambient temperature is positively associated with the occurrence of Campylobacter. Although the incidences of salmonellosis decreased from to in Germany, in , the number of infections was higher than in [ 24 ]. This shows that the success of activities to reduce the incidence cannot be taken for granted.

The incidence of clinical toxoplasmosis ranged from 6 to 23 cases in the years — [ 24 ] and thus remains well below the incidence of Salmonella and Campylobacter. Since this survey was conducted by a commercial online survey company and included target panels with a stratified sample, the survey could be conducted with little effort in a short amount of time. The number of necessary participants was quickly reached, and time-consuming recruitment was not necessary. In addition, the acceptance among the participants was high, as they consciously decided to be participants in a panel, and the questionnaire could be answered online at any time of day and at any place.

Data input and transmission were performed automatically so that transmission errors could be minimized. However, this did not insulate the study from forms of bias that are characteristic of online surveys. First, not all participant groups may be available online. In the event of queries, assistance may not be possible. In addition, the environment cannot be controlled during the survey.

The presence of third parties cannot be ruled out, nor can the presence of other media, e. Answering individual questionnaires by using automated answer scripts is theoretically possible but rather unlikely. The survey is not open to the public, and each person receives an individual e-mail link that can only be used once. Our results showed that the proportion of participants who did not know about Campylobacter at all was In the U.

In another study with an open question about pathogenic germs in food, only slightly more than half Publications from other European and non-European countries also showed that consumer knowledge of Salmonella is generally good. In Ireland, In the Netherlands, a study found that In two U. In comparison to Salmonella and Campylobacter , our results showed that the general knowledge about Toxoplasma was almost equally divided among consumers. Forty-eight percent had never heard of the pathogen, and In a study from Poland in which pregnant women participated, A survey of pregnant and postpartum women in Brazil showed that only Most of them Overall, there appear to be fewer consumer surveys than on Campylobacter and Salmonella.

This may be because clinical symptoms usually do not occur except in pregnant women. In addition, the overall case numbers are significantly lower than those for Campylobacter and Salmonella in Germany as well as throughout the EU [ 33 ].

Our study showed that meat was not sufficiently known as the main vector of Campylobacter. Only half Although consumers indicated that they knew how they could protect themselves, In general, consumers are aware that food-borne infections are often associated with chicken meat [ 34 , 35 ], but an international comparison also shows that consumers do not know that meat is a vector of Campylobacter.

A study from Switzerland showed a high level of general knowledge about pathogenic bacteria in poultry meat, but pathogenic bacteria are perceived as the least threatening in comparison to other potential food risks, such as the intake of too many calories, an unbalanced diet, hormone residues in meat or allergies [ 37 ].

Our study also showed that meat was predominantly known as a vector of Salmonella. Only Nevertheless, it was found that some consumers misjudged their knowledge. Of those who said they knew how to protect themselves, An international comparison shows that many consumers are aware that meat can be a source of Salmonella transmission. A survey of students at the University of Maine showed that slightly more than half of those surveyed Murray and Glass-Kaastra [ 34 ] showed that the majority of respondents are aware of the risks of foodborne illness associated with chickens, and the majority are aware that chickens that are not fully cooked can be a cause of foodborne illness.

In an Italian study, on the other hand, the awareness of Salmonella transmission was not particularly high. In Ireland, a study showed that of those who knew about Salmonella , only Only 4. In our study, Thus, we can conclude that consumers know more about the transmissibility of Toxoplasma via meat than about the transmissibility of Campylobacter via meat. Another U. In a study from Poland that included only pregnant women, Since the consumption of meat is known to be the main cause of C ampylobacter infection, a reduction in meat consumption could lead to a reduced incidence of Campylobacter food-borne infections.

A general reduction in meat consumption would also have the advantage of a lower number of Salmonella and Toxoplasma infections, although consumer knowledge of these pathogens is higher.

Clinically manifest diseases or even deaths associated with the consumption of meat, and therefore secondary health care costs, may be reduced if knowledge about foodborne diseases were more widespread.

Switching to a vegetarian diet would also reduce infection with these pathogens, as meat is the most common source of foodborne infections. A complete reduction in incidence is not possible because Campylobacter is also transmissible through raw milk [ 3 ] and Salmonella through eggs [ 33 ].

In addition, only Thus, it is not sufficient only to increase the level of knowledge about Campylobacter. In Germany, there are still too many consumers who do not wash their hands or the cutting board after preparing raw meat [ 41 ]. International comparative studies show that consumers are well aware of good hygiene practices and that many consumers are familiar with hygiene measures, such as washing their hands after handling raw meat [ 43 , 44 ].

One reason for the nevertheless increasing incidence of foodborne infections in general could be that consumers do not wash their hands properly, and cross-contamination still occurs [ 45 ]. Health policy has long recognized that insufficient consumer awareness of Campylobacter is a problem, and scientific institutions have already compiled comprehensive information for consumers.

However, although much information about Campylobacter and protection against infection is available at the national and international levels [ 46 , 47 , 48 , 49 ], our results suggest that the available information does not reach consumers.

Consumers must actively search for available information material. Increased media attention could increase consumer awareness and vigilance in food handling [ 44 ].
