The recall affects 11 German states and comes after thousands of Dutch eggs were recalled in Germany because of renewed fipronil contamination.
Some 73,000 Dutch eggs were withdrawn from sale in Germany after more fipronil contamination was found in eggs from the Netherlands – a year after the original scandal.
Fipronil has been found on two Dutch farms in the latest scare and the authorities expect that it will be confirmed on a third.
According to the German Government site, the salmonella contamination has affected the states of Baden-Wurttemburg, Bavaria, Berlin, Brandenburg, Bremen, Hamburg, Hesse, Mecklenburg-Vorpommern, Lower Saxony, North Rhine-Westphalia, Saxony and Schleswig-Holstein. The infections were reportedly discovered during a routine testing procedure.
The infected organic eggs were stocked by several major German retailers, including Penny, Kaufland, Aldi Nord, Aldi Sued, Real, Lidl and Netto.
Darko Janjevic of DW reports German authorities launched a probe into a string of deaths at a metal fittings company after an employee was caught trying to poison a co-worker’s lunch. Police found quicksilver, lead and cadmium in the man’s home.
The man was arrested for the incident in the town of Schloß Holte-Stukenbrock, northwest Germany. However, police now suspect he may be responsible for up to 21 deaths of people working for the same company.
The police detained the 56-year-old suspect in May this year, after one of his co-workers noticed an unknown white powder on his food. The would-be victim alerted his superiors and asked them to review the recordings made by security cameras, which then showed the suspect adding the substance to the co-worker’s lunch.
“In the beginning we thought it was a misconceived prank between co-workers, and not a murder attempt,” said Tilo Blechinger, the manager for the metal fittings manufacturer ARI Armaturen, to the DPA news agency.
The case escalated to an attempted murder after authorities identified the powder as lead acetate, a highly toxic and nearly tasteless substance that could cause serious organ damage.
Repetition is the norm. Karl Popper had something to say about that.
In 2004, my laboratory reported (and by reported I mean published in a peer-reviewed journal) that, based on 60 hours of detailed viewing of television cooking shows, an unsafe food handling practice occurred about every four minutes, and that for every safe food handling practice observed, we observed 13 unsafe practices. The most common errors were inadequate hand washing and cross-contamination between raw and ready-to-eat foods.
Once the paper was published, it made headlines around the globe.
They then tested two groups of participants making chicken salad with home-made mayonnaise based on a cooking video – one of which showed a chef who followed recommendations and another which showed a cook with poor hygiene.
Those shown the video with the exemplary kitchen hygiene complied with the recommended measures more frequently when cooking the dish by themselves.
Prof Hensel added: “The results show that the kitchen hygiene presented in cooking shows may have an influence on the hygiene behaviour of the viewers.
“TV cooking shows can therefore take on a role model function by sharpening awareness of kitchen hygiene instead of neglecting it.”
Consumers receive information on food preparation from a variety of sources. Numerous studies conducted over the past six years demonstrate that television is one of the primary sources for North Americans. This research reports on an examination and categorization of messages that television food and cooking programs provide to viewers about preparing food safely. During June 2002 and 2003, television food and cooking programs were recorded and reviewed, using a defined list of food safety practices based on criteria established by Food Safety Network researchers. Most surveyed programs were shown on Food Network Canada, a specialty cable channel. On average, 30 percent of the programs viewed were produced in Canada, with the remainder produced in the United States or United Kingdom. Sixty hours of content analysis revealed that the programs contained a total of 916 poor food-handling incidents. When negative food handling behaviors were compared to positive food handling behaviors, it was found that for each positive food handling behavior observed, 13 negative behaviors were observed. Common food safety errors included a lack of hand washing, cross-contamination and time-temperature violations. While television food and cooking programs are an entertainment source, there is an opportunity to improve their content so as to promote safe food handling.
An explosive increase of CPC isolated from rectal swabs of patients during weekly routine screening led to the declaration of an outbreak. A hospital-wide prevalence screening was initiated as well as screening of all patients on admission and before transfer to another ward, and canteen staff, patient rooms, medical and kitchen inventory and food. Swabs were streaked out on selective plates. All CPC isolates were analysed by mass spectrometry and selected isolates by whole-genome sequencing.
In total, 76 mostly unrelated cases in different wards were identified. The CPC was isolated from retained samples of prepared vegetable salads and puddings and from a mixing machine used to prepare them only after an overnight culture. The immediate ban on serving potential source food resulted in a sharp decline and finally disappearance of novel cases. Repeated testing of pre-sliced vegetables showed a high degree of contamination with C. freundii without a carbapenemase, indicating a possible source.
This report demonstrates that an explosive increase in carbapenemase-expressing Enterobacteriaceae contamination may be caused by a foodborne source, and suggests that pre-sliced vegetables have to be taken into account as a putative pathogen repository. It also underlines the importance of appropriate cooling, transport, re-heating and distribution of meals and indicates that probing of non-organic surfaces is limited by low sensitivity, which may be increased by additional overnight cultivation in appropriate media.

Associated Press reports that German authorities said Saturday they are confident that a 53-year-old man arrested a day earlier is behind a blackmail attempt that saw jars of poisoned baby food placed on store shelves in southern Germany.
Prosecutors said investigators found the same poison — ethylene glycol, a compound used in antifreeze — when they arrested the man Friday near the southwestern city of Tuebingen.
Chief prosecutor Alexander Boger told a news conference in Konstanz, on Germany’s southern border, that the man hadn’t confessed but the evidence against him was substantial.
DNA found on the baby food jars and pictures taken with a supermarket surveillance camera also pointed to the suspect, who wasn’t identified due to German privacy rules, prosecutors said.
Authorities and companies received an email this month threatening to poison unspecified food at German retailers inside the country and beyond unless more than 10 million euros ($11.8 million) was paid by Saturday.
The blackmailer alerted authorities that five jars of baby food at shops in Friedrichshafen, near Konstanz, had been tampered with. Officials located the jars and found they contained ethylene glycol but said there’s no evidence that anyone was poisoned.
We investigated 543 Listeria monocytogenes isolates from food having a temporal and spatial distribution compatible with that of the invasive listeriosis outbreak occurring 2012–2016 in southern Germany. Using forensic microbiology, we identified several products from 1 manufacturer contaminated with the outbreak genotype. Continuous molecular surveillance of food isolates could prevent such outbreaks.

We report an ongoing, protracted and geographically dispersed outbreak of hemolytic uremic syndrome (HUS) and gastroenteritis in Germany, involving 30 cases since December 2016. The outbreak was caused by the sorbitol-fermenting immotile variant of Shiga toxin-producing (STEC) Escherichia coli O157.
Molecular typing revealed close relatedness between isolates from 14 cases. One HUS patient died. Results of a case–control study suggest packaged minced meat as the most likely food vehicle. Food safety investigations are ongoing.

Two cases of botulism in the province of Alicante and another in Germany linked to a brand of dried salted fish produced in The Netherlands has led to it being withdrawn from sale in various parts of Spain.
Salted roach (rutilus rutilus, known in Spanish and branded as such in supermarkets asrutilo), stocked in refrigeration cabinets and bearing the identification number NL-6114-EG, distributed by Monolith Alimentos España Sur (in Valencia) and Norte (in Catalunya) has been taken off the shelves after two consumers in the province of Alicante reported having been apparently affected by the bug.
Both showed ‘very similar symptoms’, although it has yet to be confirmed whether they caught botulism from eating dried roach.
All supermarkets and delicatessens in the towns of Dénia, Altea, La Nucia, Torrevieja, Benidorm, Orihuela and Alicante city have taken it off the shelves, as have those in the province of Castellón, Gandia (Valencia province) and Valencia city.
In Catalunya, shops in Barcelona, Badalona and Sabadell (Barcelona province), Salou (Tarragona province) and Lleida have withdrawn it from sale.
The Spanish Consumer, Food Safety and Nutrition Agency (AECOSAN), part of the ministry of health, says it has received a European alert after a case of botulism in Germany thought to have been caused by the same product.
The mammalian gut harbors thousands of microbial species – collectively known as the microbiota or microbiome – that interact with each other and with their host to form a complex ecosystem.
In healthy organisms, this community provides an effective shield against infection by many pathogenic organisms, such as Clostridium difficile (which is responsible for antibiotic-associated diarrhea) and various Salmonella species.
Researchers led by LMU microbiologist Professor Bärbel Stecher, in cooperation with colleagues from the University of Vienna and the Technical University of Munich, now show that, in the mouse, a defined group of 15 bacterial species confers the same degree of protection against Salmonella infections as does the host’s natural microbiota. The work establishes a new model system for the investigation of the interaction between the gut microbiome and infectious pathogens, which could in turn provide new approaches to the treatment of gastrointestinal infections. The new findings appear in the journal Nature Microbiology.
The protective effect provided by the gut microbiota against infection by invasive pathogens is referred to as colonization resistance. Exposure to antibiotics can disrupt this mechanism because these drugs typically alter the composition of the bacterial population in the gastrointestinal tract. “However, the contribution made by individual bacterial species to colonization resistance remains unclear,” says Stecher, who is also member of the German Center for Infection Research (DZIF).
“In order to gain a better understanding of the functions of the gut microbiota in this context, we had already established in my laboratory a minimal consortium comprising 12 bacterial species which are representative for the gut microbiome of the mouse.” This set of species, which is referred to as Oligo-MM-12, can be introduced into germ-free mice and is stably maintained over several generations. However, while mice colonized by the Oligo-MM-12 species are more resistant to infection by Salmonella enterica than their germ-free relatives, they are not as well protected as mice with a normal microbiome.
The team then went on to develop a new strategy, called genome-guided microbiota design, to identify species required to confer the same measure of protection as the natural gut microbiome of the mouse.
“We compared DNA sequences from the 12 species represented in Oligo-MM-12 with homologous sequences derived from the total mouse microbiome, and were able to identify groups of genes that were missing from our set,” Stecher explains. Some of these genes turned out to be characteristic for so-called facultative anaerobes, i.e. bacterial species that grow best in the presence in oxygen, but are nevertheless capable of proliferating in its absence. Indeed, the genus Salmonella consists of facultative anaerobes, while almost all the species that make up the Oligo-MM-12 consortium are obligate anaerobes – for which oxygen is toxic.
“We therefore supplemented our original consortium with three facultatively anaerobic species that are found in the microbiota of healthy mice,” Stecher says, “and we were able to demonstrate experimentally that this combination confers the same level of colonization resistance against Salmonella as that observed in mice that have a natural microbiota.” Stecher and her colleagues believe that their new “mini-microbiota”, together with the use of genome-guided microbiota design, provides a powerful new tool for the identification of hitherto unknown functions mediated by natural microbiota. This opens a route to the identification of specific bacterial species that could ameliorate the effects of disease-dependent dysfunction of the gut microbiota.
