This study provides an important insight into the response of food safety systems during the first months of the pandemic, elevating the perspective of preventing Covid-19 within conventional food safety management systems. A multi-country survey was conducted in 16 countries involving 825 food companies. Based on the results of the survey, it is obvious that the level of maturity of a food safety system in place is the main trigger in classifying companies and their responses to the pandemic challenge. Staff awareness and hygiene are the two most important attributes in combating Covid-19, opposed to temperature checking of workers in food establishment and health protocols from the World Health Organization, recognized as attributes with limited salience and importance. Companies confirmed implementation of more restrictive hygiene procedures during the pandemic and the need for purchasing more additional personal protective equipment. Retailers were identified as the food supply chain link mostly affected by the pandemic opposed to food storage facilities ranked as least affected. During this challenging period, all companies declared that food safety has not been compromised at any moment. It is important to note that less than a half of the food companies had documented any emergency plans associated with pandemics and health issues in place.

The purpose of this study was to assess the functional and prognostic correlates of B-lines during stress echocardiography (SE). BACKGROUND B-profile detected by lung ultrasound (LUS) is a sign of pulmonary congestion during SE. METHODS The authors prospectively performed transthoracic echocardiography (TTE) and LUS in 2,145 patients referred for exercise (n ¼ 1,012), vasodilator (n ¼ 1,054), or dobutamine (n ¼ 79) SE in 11 certified centers. B-lines were evaluated in a 4-site simplified scan (each site scored from 0: A-lines to 10: white lung for coalescing B-lines). During stress the following were also analyzed: stress-induced new regional wall motion abnormalities in 2 contiguous segments; reduced left ventricular contractile reserve (peak/rest based on force, #2.0 for exercise and dobutamine, #1.1 for vasodilators); and abnormal coronary flow velocity reserve #2.0, assessed by pulsed-wave Doppler sampling in left anterior descending coronary artery and abnormal heart rate reserve (peak/rest heart rate) #1.80 for exercise and dobutamine (#1.22 for vasodilators). All patients completed follow-up. RESULTS According to B-lines at peak stress patients were divided into 4 different groups: group I, absence of stress B-lines (score: 0 to 1; n ¼ 1,389; 64.7%); group II, mild B-lines (score: 2 to 4; n ¼ 428; 20%); group III, moderate B-lines (score: 5 to 9; n ¼ 209; 9.7%) and group IV, severe B-lines (score: $10; n ¼ 119; 5.4%). During median follow-up of 15.2 months (interquartile range: 12 to 20 months) there were 38 deaths and 28 nonfatal myocardial infarctions in 64 patients. At multivariable analysis, severe stress B-lines (hazard ratio [

Foodborne zoonoses have been estimated to annually affect 10% of the global population, among which zoonotic parasites constitute an important class of aetiological agents. The major meatborne parasites include the protozoa Toxoplasma gondii and Sarcocystis spp., and the helminths Trichinella spp. and Taenia spp., all of which may be transmitted by pork. The significance of zoonotic parasites transmitted by pork consumption is emphasized by the prediction by the Food and Agriculture Organization of an 18.5% increase in world pork production over the next 10 years. Of all the porkborne parasites, the three 'T' parasites have been responsible for most porkborne illness throughout history; they are still endemic, and therefore are important public-health concerns, in developing countries. Although the risk of porkborne parasites, particularly helminths, may currently be considered insignificant in developed countries, the modern trend of consuming raw meat favours their re-emergence. This paper overviews the main parasites transmitted to humans by pork, and outlines the main lines of prevention.

The efficacy of atovaquone (ATO) combined with clindamycin (CLI) against Toxoplasma gondii was examined in murine models of infection with a mouse-non-virulent (Me49) strain. Swiss-Webster mice inoculated by mouth with 10 or 20 cysts were treated with ATO and CLI alone or combined at dosages of ATO 5-100 and CLI 25-400 mg/kg/day for 2-4 weeks. Drug treatment was initiated (i) day 4 post-infection (acute infection), (ii) 3 months post-infection (chronic infection) and (iii) following a 2-3 week course of treatment with dexamethasone (DXM) alone or combined with cortisone-acetate (CA) introduced 3 months post-infection (reactivated toxoplasmosis). In acute infection, whereas treatment with any drug or drug combination significantly enhanced survival and reduced the brain cyst burden, in mice treated with ATO alone or combined with CLI, the cyst counts were significantly lower than in mice treated with CLI alone. In chronic infection, the decrease in the cyst burden observed 2 weeks after treatment with either drug alone was significant only in mice treated with the combined drugs. Most importantly, in reactivated toxoplasmosis, whereas an effect for the combined drugs was shown in mice suppressed with both DXM alone and combined with CA, in mice pre-treated with DXM a 3 week course of ATO > or = 25 and CLI 50 mg/kg/day significantly increased survival and markedly decreased the cyst burden. The latter effect was long-term, since the cyst burdens in treated mice continued to decrease up to 3 months later, whereas they increased in the untreated mice. The results warrant clinical evaluation of the combination of ATO and CLI in the treatment of toxoplasmosis in both immunocompetent and, more importantly, immunosuppressed patients.
