Higher temperatures has been shown to increase the incidence of gastrointestinal infections:
Foodborne illness has declined 17% overall in
Australia but the number of Salmonella
and Campylobacter cases has risen, every
1°C above the mean of the previous month rise in temperature sustained over 8
days.
Australian
National University research tracked changes between 2000 and 2010. Findings
should assist policy makers to improve regulation and control of foodborne
disease for specific pathogens, said the researchers. Increased temperature has
been shown to increase the incidence of gastrointestinal infections: a 2.48%
increased risk of gastroenteritis has been demonstrated for every 1°C above the
mean of the previous month rise in temperature sustained over 8 days.
Foodborne
illness caused an estimated 4.1 million illnesses, 30,600 hospitalizations, and
60 deaths in 2010. The figure for illnesses circa 2000 was 4.3 million.
Millions of cases unidentified causes: Of the total illnesses 0.8 million
were caused by 18 pathogens but the remaining 3.3 million had unknown or unidentified
causes. The rate of foodborne campylobacteriosis was 13% higher in 2010 than
2000 and salmonellosis was 24% higher in the same period.
Pathogenic E.coli, Norovirus, Campylobacter and non-typhoidal
Salmonella were responsible for 93%
of the foodborne illnesses caused by known pathogens.
Contaminated
food also caused 5,140 cases of non-gastrointestinal illness circa 2010. Toxoplasmosis was the most common foodborne
non-gastrointestinal illness with 3,750 cases each year. Listeria monocytogenes and non-typhoidal Salmonella infections were the leading causes of death.
In Australia from 2006 onward, the number of raw egg–associated salmonellosis outbreaks has markedly increased and since 2000, the numbers of notified laboratory-confirmed cases of campylobacteriosis and salmonellosis have increased,” said the researchers.
Estimates
of Rotavirus cases for circa 2010
were lower than those for circa 2000, reflecting the success of the vaccination
program. Also, the estimated number of foodborne illness cases caused by Hepatitis A virus declined from 150
cases/year to 40 cases/year circa 2010, reflecting improved disease control
through vaccination.
Refined methods: The researchers said methods to calculate
estimates were refined and in the intervening years, surveillance has improved
and data availability has increased. Underreporting multipliers were used to
estimate the community incidence of foodborne illness for infected people who
did not seek treatment or submit specimens for testing.
