Abstract
Botulism is a fatal neurologic disease caused by the botulinum toxin (BoNT) produced by Clostridium botulinum. It is a rare but highly toxic disease with symptoms, such as cramps, nausea, vomiting, diarrhea, dysphagia, respiratory failure, muscle weakness, and even death. Currently, two types of antitoxin are used: equine-derived heptavalent antitoxin and human-derived immunoglobulin (BabyBIG®). However, heptavalent treatment may result in hypersensitivity, whereas BabyBIG®, has a low yield. The present study focused on the development of three anti-BoNT monoclonal antibodies (mAbs), 1B18, C25, and M2, in Nicotiana benthamiana. The plant-expressed mAbs were purified and examined for size, purity and integrity by SDS-PAGE, western blotting and size-exclusion chromatography. Analysis showed that plant-produced anti-BoNT mAbs can fully assemble in plants, can be purified in a single purification step, and mostly remain as monomeric proteins. The efficiency of anti-BoNT mAbs binding to BoNT/A and B was then tested. Plant-produced 1B18 retained its ability to recognize both mBoNT/A1 and ciBoNT/B1. At the same time, the binding specificities of two other mAbs were determined: C25 for mBoNT/A1 and M2 for ciBoNT/B1. In conclusion, our results confirm the use of plants as an alternative platform for the production of anti-BoNT mAbs. This plant-based technology will serve as a versatile system for the development botulism immunotherapeutics.

Abstract
Food-borne botulism is a rare but potentially fatal illness. Its management depends on rapid diagnosis and prompt antitoxin administration. However, diagnosing food-borne botulism can be challenging at an early stage. Here, we report a 62-year-old male with food-borne botulism. The patient presented with extremity muscle weakness, dyspnea, bilateral droopy eyelids (more significant on the right side), dysarthria, and progressive dysphagia. The electromyography indicated presynaptic membrane abnormalities. The toxicology screen reported a positive result for botulinum toxin type A. He received plasma exchange, botulism antitoxin, and supportive care. However, he had a cardiac arrest six days later. Spontaneous circulation was restored after immediate cardiopulmonary resuscitation. The patient gradually recovered his muscle strength and could have complete eyelid elevation. A detailed interview revealed that six family members developed similar symptoms. All of them consumed a homemade sauce prepared three years ago. They all tested positive for botulinum toxin type A. Two of them had cardiac arrests. Therefore, family aggregation could happen to botulism. Careful interviews, early diagnosis, and timely administration of botulism antitoxin are the keys to saving lives. Special attentions should be given to the cardiac evaluations since botulism can cause cardiac arrest and death.

Abstract
Food safety constitutes a basic priority for public health. Foodborne botulism occurs worldwide; it is an acute paralytic disease caused by the consumption of food containing the botulinum toxin. Growing consumer demand for cheese products could result in increased exposure of the population to this toxin, and thus the risk of foodborne botulism. The majority of cases of botulism caused by dairy products are related to cheese products specifically. Epidemic outbreaks and isolated cases have been reported over time. Domestically canned foods are still among the primary causes of the disease. Cheese products are not regularly involved in botulism incidents; it is however, necessary to take control measures for manufacturing and domestic preparation due to the high risk of occurrence of this particular disease. The aim of this review is to discuss foodborne botulism caused by cheese products, providing a brief epidemiological history, and to examine certain control measures that should be taken throughout the production process to better protect public health.
